M5: Escape leaves a Fill & Sign tool, as it leaves a comment tool (#4539)

* Escape leaves a Fill & Sign tool, as it leaves a comment tool

The first Escape closes the open type box, the next one goes back to
Select; Fill & Sign's Text tool otherwise opened a box at every click with
no way out by the keyboard.

* Fill & Sign: a new text box deselects, so two presses of Escape close it and leave the tool
