New Identity hotkey/keyboard shortcut (Ctrl+Shift+U) is inhibited while cursor is in a text box

Since the TBB 8.0 update, I now use the keyboard shortcut/hotkey to select New Identity (previously I used the menu path in the TorButton, whose removal I believe is misguided - but I digress).

But the hotkey doesn't work if the text cursor is in a text input area on a web page, it seems. And in some cases it even just outputs the letter "U" into that input, which is potentially even a fingerprinting information leak in some contexts. It also jeopardizes users who may have to quickly conceal their private activities, who would use this keyboard shortcut as a kind of "Boss Key" as was found on old computer games.

I believe that this hotkey should work at all times and in all contexts as long as a Tor Browser window is in focus.

Thank you to all who contribute to this wonderful and important project. Do not be dissuaded from your courageous work.
