* Adjust margin for sticky elements on modal
Previously white space was visible to the right of sticky elements due to right padding being added to the body. This fixes#23661.
* Add unit tests for margin of sticky elements on modal
When one uses say a carousel inside a tab, the `.active` selector previously matches the carousel ones too leading to broken tabs.
It's not the perfect solution but should the job for now.
Part of an update to align the naming schemes across our components.
- Renames .popover-title to .popover-header
- Renames .popover-content to .popover-body

Same hack as in https://github.com/twbs/bootstrap/pull/22426 (modulo the selector, which is wrong in that PR and will be updated in a separate PR) to get tooltips to work correctly on iOS. Dynamically adds/removes empty (`noop`) `touchstart` event handlers to all children of `<body>` in order to coax iOS into proper event delegation/bubbling
* Add carousel mouse listeners even if touch events enabled
- touch events are enabled not just on "mobile", just also on
touch-enabled desktop/laptop devices; additionally, it's possible to
pair a mouse with traditionally touch-only devices (e.g. Android
phones/tablets); currently, in these situations the carousel WON'T pause
even when using a mouse
* Restart cycle after touchend
as `mouseenter` is fired as part of the touch compatibility events, the
previous change results in carousels which cycle until the user
tapped/interacted with them. after that they stop cycling (as
`mouseleave` is not sent to the carousel after user scrolled/tapped
away).
this fix resets the cycling after `touchend` - essentially returning
to the previous behavior, where on touch the carousel essentially never
pauses, but now with the previous fix it at least pauses correctly for
mouse users on touch-enabled devices.
includes documentation for this new behavior.
