Incompatible TextArea and Button configurations

[mstijak]

We made a recent change so that buttons do not receive focus on mousedown.
On the other side, by default, TextArea relies on blur event to propagate changes.

The problem occurs when the button is clicked while textarea is focused. Focus stays within the textarea and change is not propagated.

All widgets should work out of the box, so either change the defaults so TextArea submits on every input or focus buttons on click.

Maybe a better solution would be to switch move focus to the body instead of just calling e.preventDefault().

Resolved: focus moves to the body.
