Hi,
I'm not so sure about the pointer_set_focus here. Shuffling surfaces is
supposed to trigger a repick, which will reassign the pointer focus.
However, it seems something is off. The keyboards focus is different to
pointer focus, because keyboard focus is "sticky" and needs to be
explicitly managed. Pointer focus generally follows picking unless the
pointer is grabbed.

This was made with weston-terminal patched to have a "minimize" option
in the context menu. I just pushed that patch to master, btw. so
everyone can test.
I assume the first wl_pointer.leave(nil) is for the popup surface, so
that's ok. The enter for nil looks very suspicious though. Maybe that
is caused by this patch?
My opinion is that this looks okay apart from the pointer focus.

Just curious, how can the surface go off-center? Some output
hot-unplugging involved?
When wouldn't there be a black_view?
