Palette: handle the case where setting the transient window does fail, SL #4221

Browse Source 
The expected parent window did likely change, for example
this can happen when we switch the Home Views while a Palette
of a canvas icon is popping up (SL #4221). In that case
send the 'popdown' signal so that for example the hovering
state feedback can be cleared.
