see overlayer.py:155

in preliminary tests, using a textbubble in a gtk.layout, the widget stacking order was not kept.
More simply, adding a bubble, then a button over it, the button gets the events as it is over the bubble, but the bubble is drawn over the button. This is not desirable behaviour.

This task is about testing if the new "improved" textbubble still suffer from this bug (as it may not).
Then, fixing it could be good, if it doesn't requires too much effort, else postpone it far in the future.
But this is mainly a testing bug.
