34 is affected... is 33?

(and are we sure this isn't youtube blocking keypresses or something silly?)

OK, so at least it's not a new regression we're shipping compared to current release...

That doesn't really answer the question, unfortunately.

This is because youtube calls preventDefault() on the keypress event for the ctrl/cmd-c. Simple testcase:

which makes this a dupe.

Thinking about this more... Karl, do we have contacts at youtube to get this addressed on their end? They really shouldn't be calling preventDefault on keypresses with modifier keys pressed.

Youtube/Google has been contacted.
