Fix #35340: 3D manipulator not working right after undoing with cmd+Z on OS X.

Another issue with the recent Ghost changes here. For some reason key up events
are not coming through when the command key is pressed. I can't figure out why,
for now just always handle them, still fixes the original bug.
