If I set a text box / textarea with a keydown listener and want to cancel ctrl+tab, it is not cancelled.  I have to wait around for the keypress event to do it.  This doesn't seem nice from an architectural point of view.

Use case:  I'm writing a keyboard remapper for textareas and when I get keyboard entry, if it's to be remapped, I supply the new action in the keydown event, and if such action is supplied, the original keydown event is cancelled.  This architecture has been working fine, except for ctrl+tab I should have to go into a special mode just to eat the next keypress event.  This strikes me as awkward.

Perhaps there are other such key combinations requiring keyPress cancellation, but I don't know of any so that is the other reason I find this so peculiar.

Reproducible: Always

Steps to Reproduce:
See the attachment.  You can set it either to cancel the ctrl+tab keydown or keypress event.  Just make sure there is another tab in the window and that focus is in the textbox.


Expected Results:  
I expect that cancelling the keydown event on ctrl+tab will cancel the default action of switching to another tab.

Attachment: cancel of ctrl+tab keydown still leads to tab switch
