ALT key doesn't stopPropagation

Veröffentlicht

With the new version 50.1.0 Alt key doesn't stop propagation / prevent default, and ALT was captured by the browser MENU. In others words I don't get KEYUP event, just key down, and with ALTGr it seems the same behaviour, but MENU doesn't get focus, just get ALT keydown, CTRL keydown, CTRL keyup, (missing ALT Keyup).

With the previous version 48.0.2 (before update) was working perfect, all events are triggered.
