We don't map Mod3 to MOD3 and Mod2 to NUMPAD in GetEventFlagsFromXState() (in
ui/events/x/events_x.cc). Should we?

Mod3Mask, yes; it's set when the caps lock key is down, as distinct from
CapsLock, which is set when caps locking is active, which I didn't realize until
it caused a regression, so that is already in another CL:
https://codereview.chromium.org/277443004/

Mod2Mask is not present on input because Chrome doesn't manage NumLock state. It
does get set in the outgoing X11 events.
