Fixes 2 bugs:

1. All keydowns were being prevented. Because of that the user wasn't able to navigate in the whole page using ARROW_UP/ARROW_DOWN.

2. Even when  is an input or textarea the keydowns were being prevented. Because of that the user wasn't able to type any text on these elements.

* Throw error when a plugin is in transition
* Add unit tests about plugins in transition

When the rubberband effect causes Safari to scroll past the top of the
page, the value of scrollTop becomes negative. If the offset of the first
ScrollSpy target is 0 - essentially if the target is at the top of the
page - then ScrollSpy should not clear the active item. Conceptually, the
first item should remain active when rubberbanding past the top of the
page.

This commit fixes issue #21055 by verifying the first scrollspy target is
not at the top of the page before clearing the active nav-item.

* Fix bug with dropdown tab links not deactivating when other tab or dropdown link is clicked

* Revise bug fix for more stability

Instead of doing a new assert.async(), just do a single one for the entire test
and let the .then() be async as well.

* Use $.one() instead of $.on() since there are no $.off()s in the code.
* Remove unnecessary namespacing of listeners for the `scroll` & `load` events.
    These are vanilla DOM events (not custom jQuery namespaced events)
    and we're not using jQuery namespacing to manage these event listeners either (e.g. `$.off()`).

js/tests/index.html: Replace jQuery event alias methods with functions that throw explanatory errors, instead of with undefined

Bootstrap’s .button styles can be applied to other elements, such as labels, to provide checkbox or radio style button toggling.

When the checkbox or radio state is changed, there should be triggered the change event. Currently, the change event is triggered on the Button, which is not correct. Only input fields do support the change event.
