The edge cases will get you. One issue (so far) with this is that if you Tab
with an invalid value (focus is lost and regained), then follow up with an
Esc, the committed value will be the invalid one. I might be able to live
with this. If I call preventDefault in the OTHER case, I don't have that
issue, but then the editor regains focus but without the current (invalid)
value.
