Transitionend with bootstrap 4

Created by: 719media

When looking into the necessity of $.support.transition.end, it seems to be that this is no longer needed.

I see that some properties were removed here:

https://github.com/twbs/bootstrap/pull/24511

But webkitTransitionEnd remains. However, according to https://caniuse.com/#feat=css-transitions, all browsers that bootstrap 4 supports use transitionend just fine. Is this even needed anymore?
