Comment 6 for bug 1646257

As an experiment, I made the following changes in editablelabel.py:

- __init__(), line 48-ish: added a self._label.set_text("blah") just to get a default label (not necessary)

- set_text(), line 65-ish: removed the call to self._label.set_text(text).

Even with the titlebars switched on (the default) it becomes buggy with these changes.

Looks like setting the title label triggers a series of Gtk+ geometry recomputations which finally results in the correct layout; omitting this step optimizes away some recalculations and somehow certain Gtk+ events are then not acted upon immediately.

(At this point I cannot promise at all that I'll have time to continue investigating.)
