The panel is not a window, so sub-surfaces can be made to work there
well enough.

It is for normal windows like registered with xdg_shell where
sub-surfaces are not suitable for tooltips. A sub-surface is a part of
the window, not another window. A tooltip is not expected to change the
window geometry, but a sub-surface does count into the window geometry.
Extruding sub-surfaces therefore affect the (parent) window geometry. It
is in the protocol spec.
