Previously deprecated in v4.x, this clears out the now unused Sass option and removes some unused mixins. Arguably we could remove more, but I like the hover-focus mixin and we make extensive use of it across the project.

// In order to support the browser's form validation feedback, powered by the

// `required` attribute, we have to "hide" the inputs via `clip`. We cannot use
|
|
// `display: none;` or `visibility: hidden;` as that also hides the popover.
|
|
// Simply visually hiding the inputs via `opacity` would leave them clickable in
|
|
// certain cases which is prevented by using `clip` and `pointer-events`.
|
|
// This way, we ensure a DOM element is visible to position the popover from.
