Patrick H. Lauke be80d26cdb Ensure button plugin sets/removes active class correctly on page load (#28952)
* Ensure correct active class is set on button toggles/checkboxes/radios on page load

Sanity check, ensures that the UI visually matches the actual values/states of controls. Also ensures that if any autocomplete/autofill happened, this is visually accounted for
by having the correct class set.

Includes unit tests (and `autocomplete` has been removed from these as it's no longer necessary)

* Remove now unnecessary autocomplete attribute

As the attribute was there to force/ensure that the visual presentation matched the state, and this is now taken care of programmatically, there's no need to unnecessarily suppress autocomplete...let them autocomplete if they want to...

## How it works
Progress components are built with two HTML elements, some CSS to set the width, and a few attributes. We don't use [the HTML5 `<progress>` element](https://developer.mozilla.org/en-US/docs/Web/HTML/Element/progress), ensuring you can stack progress bars, animate them, and place text labels over them.
- We use the `.progress` as a wrapper to indicate the max value of the progress bar.
- We use the inner `.progress-bar` to indicate the progress so far.
- The `.progress-bar` requires an inline style, utility class, or custom CSS to set their width.
- The `.progress-bar` also requires some `role` and `aria` attributes to make it accessible.
Put that all together, and you have the following examples.
{% capture example %}
<div class="progress">
<div class="progress-bar" role="progressbar" aria-valuenow="0" aria-valuemin="0" aria-valuemax="100"></div>
</div>
<div class="progress">
<div class="progress-bar" role="progressbar" style="width: 25%" aria-valuenow="25" aria-valuemin="0" aria-valuemax="100"></div>
</div>
<div class="progress">
<div class="progress-bar" role="progressbar" style="width: 50%" aria-valuenow="50" aria-valuemin="0" aria-valuemax="100"></div>
</div>
<div class="progress">
<div class="progress-bar" role="progressbar" style="width: 75%" aria-valuenow="75" aria-valuemin="0" aria-valuemax="100"></div>
</div>
<div class="progress">
<div class="progress-bar" role="progressbar" style="width: 100%" aria-valuenow="100" aria-valuemin="0" aria-valuemax="100"></div>
</div>
{% endcapture %}
{% include example.html content=example %}
Bootstrap provides a handful of [utilities for setting width]({{ site.baseurl }}/docs/{{ site.docs_version }}/utilities/sizing/). Depending on your needs, these may help with quickly configuring progress.
{% capture example %}
<div class="progress">
<div class="progress-bar w-75" role="progressbar" aria-valuenow="75" aria-valuemin="0" aria-valuemax="100"></div>
</div>
{% endcapture %}
{% include example.html content=example %}
## Labels
Add labels to your progress bars by placing text within the `.progress-bar`.
{% capture example %}
<div class="progress">
<div class="progress-bar" role="progressbar" style="width: 25%;" aria-valuenow="25" aria-valuemin="0" aria-valuemax="100">25%</div>
</div>
{% endcapture %}
{% include example.html content=example %}
## Height
We only set a `height` value on the `.progress`, so if you change that value the inner `.progress-bar` will automatically resize accordingly.
{% capture example %}
<div class="progress" style="height: 1px;">
<div class="progress-bar" role="progressbar" style="width: 25%;" aria-valuenow="25" aria-valuemin="0" aria-valuemax="100"></div>
</div>
<div class="progress" style="height: 20px;">
<div class="progress-bar" role="progressbar" style="width: 25%;" aria-valuenow="25" aria-valuemin="0" aria-valuemax="100"></div>
</div>
{% endcapture %}
{% include example.html content=example %}
## Backgrounds
Use background utility classes to change the appearance of individual progress bars.
{% capture example %}
<div class="progress">
<div class="progress-bar bg-success" role="progressbar" style="width: 25%" aria-valuenow="25" aria-valuemin="0" aria-valuemax="100"></div>
</div>
<div class="progress">
<div class="progress-bar bg-info" role="progressbar" style="width: 50%" aria-valuenow="50" aria-valuemin="0" aria-valuemax="100"></div>
</div>
<div class="progress">
<div class="progress-bar bg-warning" role="progressbar" style="width: 75%" aria-valuenow="75" aria-valuemin="0" aria-valuemax="100"></div>
</div>
<div class="progress">
<div class="progress-bar bg-danger" role="progressbar" style="width: 100%" aria-valuenow="100" aria-valuemin="0" aria-valuemax="100"></div>
</div>
{% endcapture %}
{% include example.html content=example %}
## Multiple bars
Include multiple progress bars in a progress component if you need.
{% capture example %}
<div class="progress">
<div class="progress-bar" role="progressbar" style="width: 15%" aria-valuenow="15" aria-valuemin="0" aria-valuemax="100"></div>
<div class="progress-bar bg-success" role="progressbar" style="width: 30%" aria-valuenow="30" aria-valuemin="0" aria-valuemax="100"></div>
<div class="progress-bar bg-info" role="progressbar" style="width: 20%" aria-valuenow="20" aria-valuemin="0" aria-valuemax="100"></div>
</div>
{% endcapture %}
{% include example.html content=example %}
## Striped
Add `.progress-bar-striped` to any `.progress-bar` to apply a stripe via CSS gradient over the progress bar's background color.
{% capture example %}
<div class="progress">
<div class="progress-bar progress-bar-striped" role="progressbar" style="width: 10%" aria-valuenow="10" aria-valuemin="0" aria-valuemax="100"></div>
</div>
<div class="progress">
<div class="progress-bar progress-bar-striped bg-success" role="progressbar" style="width: 25%" aria-valuenow="25" aria-valuemin="0" aria-valuemax="100"></div>
</div>
<div class="progress">
<div class="progress-bar progress-bar-striped bg-info" role="progressbar" style="width: 50%" aria-valuenow="50" aria-valuemin="0" aria-valuemax="100"></div>
</div>
<div class="progress">
<div class="progress-bar progress-bar-striped bg-warning" role="progressbar" style="width: 75%" aria-valuenow="75" aria-valuemin="0" aria-valuemax="100"></div>
</div>
<div class="progress">
<div class="progress-bar progress-bar-striped bg-danger" role="progressbar" style="width: 100%" aria-valuenow="100" aria-valuemin="0" aria-valuemax="100"></div>
</div>
{% endcapture %}
{% include example.html content=example %}
## Animated stripes
The striped gradient can also be animated. Add `.progress-bar-animated` to `.progress-bar` to animate the stripes right to left via CSS3 animations.
<div class="bd-example">
<div class="progress">
<div class="progress-bar progress-bar-striped" role="progressbar" aria-valuenow="75" aria-valuemin="0" aria-valuemax="100" style="width: 75%"></div>
</div>
<button type="button" class="btn btn-secondary bd-toggle-animated-progress" data-toggle="button" aria-pressed="false">
Toggle animation
</button>
</div>
{% highlight html %}
<div class="progress">
<div class="progress-bar progress-bar-striped progress-bar-animated" role="progressbar" aria-valuenow="75" aria-valuemin="0" aria-valuemax="100" style="width: 75%"></div>
</div>
{% endhighlight %}
