Yes but the dock uses it for other windows. It's maybe not a common way
to use this function and we can maybe find this bug with other apps
which are already using it.
I see this bug on other computers and this is very annoying (e.g. hard
to use correctly Nautilus and Gedit with a lot of files/lines). And this
feature is a tiny feature (personally, I never minimise my windows
thanks to the use of 4, 6 or more viewports/desktops)
