Modal close behaviour on iOS 7

[Howitzer]

When I close a modal (by any data-dismiss element) the modal "flashes" in a way that makes it appear to close, open again, and then finally close.

Tested on iOS versions 7.1.1 and 7.1.2 (iPhone 4s), in Safari, Chrome (v35), and Opera(v8).

I was also able to test with Internet Explorer on Windows Phone 8, however the flashing behaviour was not present.

Unfortunately, I do not have access to an Android device for testing to further isolate Apple.

Steps to reproduce:
On an iOS device, point your browser to http://getbootstrap.com/javascript/#modals-sizes and open a modal. Then observe it's behaviour when you close it.
(Also happens in my own project, which I think would mean it's not isolated to the Docs^^)

I can confirm that there is some flashing during modal dismissal on iOS.

Could be related to the positioning stuff we changed for scrollbars, or it could be related to the translate3d stuff. Will need to play around to find out.

Just confirmed this isn't related to the translate3d usage. Using the regular translate I see the flashing on my iPhone.

I think I've also found this isn't related to the transitionend stuff from #13786.

Punting to v4.

Is there a workaround until v4? That's quite a while to wait for an iOS bug to be fixed.
