It's unclear what the reason for first introducing the original hack here (for `[tabindex="-1"]:focus {...}`) was. Seems something that may have been useful/necessary in SuitCSS, but don't think BS ever relied on this. https://github.com/twbs/bootstrap/issues/18330
It's since been modified to only apply when the browser wouldn't apply a visible outline anyway based on its own heuristics (the `:not(:focus-visible)` part) https://github.com/twbs/bootstrap/pull/28437/
But now, thinking this through more...in browsers that do support this pseudo-selector, what this is essentially saying is redundant: don't apply outline in cases where a `tabindex="-1"` element receives focus but the browser wouldn't normally apply focus outline". at best, this is unnecessary. at worst, this actually overrides things an author may explicitly be trying to do with adding `:focus { outline: ... }` explicitly.

* Dynamic tabs: use buttons rather than links
- change docs
- add mention that tabs should be <button> elements
- tweak styles to neutralise border and background
* Update js unit and visual test accordingly
- replace links with buttons
- make one specific test that uses links instead of buttons, as we still want to support it despite it being non-semantically appropriate
- Leaving a couple of tests for now. The test for removed tabs should be redone so that tabs are removed programmatically (as the approach of having that close button inside the link is invalid and broken markup). The test for dropdowns should be removed together we actually ripping out the handling for dropdowns in the tab.js code (arguably a breaking change, though we discouraged this for a few versions and effectively "deprecated" it)
* Add isolation:isolate to prevent focus being overlapped
https://github.com/twbs/bootstrap/pull/32630#issuecomment-756015766
* Remove the margin from dropdown in favor of Popper
- Set the default margin to 0 for dropdowns (To remove the Popper's warning)
- Set the required offset in dropdown's defaults
* Remove the margin from the popover component

From initial testing, this bug doesn't seem to manifest itself anywhere in Bootstrap (since we don't just set transparent background anywhere on buttons, and when we do set explicit button styles in the more specific stylings, we already do create a custom `:focus` style anyway)

The RTL cheatsheet's dropdowns aren't positioned correctly because of RTLCSS transforming `right: auto` to `left:auto` (which conflicts with Popper positioning).
