+Subject: wayland/pointer: Check for subsurfaces when grabbing
+
+Previously, the function only returned `TRUE` if the given surface was
+equal to the given pointer's focused surface. This changes the behaviour
+to also return `TRUE` if any of the given surface's subsurfaces are
+equal to the pointer's focused surface.
