Placeholder not cleared if pasting clipboard in message window remaining inactive
Gajim git master 62cfd729.
Reported by mrDoctorWho [1].
I could reproduce this in MATE. This specific pasting mode can be activated by pressing CTRL + mouse/touchpad middle button click (or simultaneously both left and right buttons). Then text gets pasted but message window remains inactive and doesn't come into foreground.
Meanwhile I've prepared a fix.
