Subject: [PATCH 1/2] Add a global event handler for beforeinput

Also imported the input event from the UI events specifications, since that one defines it.

Fixes #4526

(This PR is directly pulled from #4530, which can't land due to IP issues.)
(This PR is a replacement for #6743, which I neglected for too long.)
