I have no problem in my images, it's just by perusing the code that I
saw that #userInterfaceTheme requires a specific handling.
What worries me is not the normal usage of #userInterfaceTheme, which
works fine, it is how technically easy it is to mess things up, although
I do not see that happening too often or at all actually. But if it
happens sometime, somewhere, it will be a silent bug difficult to diagnose.
BTW I see that the #cleanUp: method will indeed reset all stacks in
hard-coded subclasses of UserInterfaceTheme, but it will not do so for
possibly existing other subclasses. So if I create my own
MuOInterfaceTheme for example, I will also need to monkey-patch
#cleanUp:.. Maybe we should iterate long #allSubclasses?
