Handling "refocus" here and below.

Hmm, this might work for many cases but I think this approach is not a straight
forward way.
I think we should introduce OnActiveInputTargetChanged() callback instead of
OnTextInputTypeChanged() into Blink (and also omnibox), then propagate to the
IME.
But this approach requires big work for many places, so I think TODO is fine for
at this moment.

Also please note that input focus can be changed by JavaScript or TAB key.

Just Omnibox, or every other native textbox, like the find bar?

But yes, it seems bad to have this change in such a fundamental part of the UI
code, but it also seems like other IME event stuff is handled here.
I'll introduce the TODO after I see what kevers@ does about the API namespace...

And then after this lands I'll start an email thread with you and you can guide
me through the changes needed in Blink (where I'm not familiar).
