A shot in the dark since I don't own a touch enabled monitor:

Test 1:

 Add `GDK_SCROLL_MASK` on the original `gdk_pointer_grab` function;

Test 2:

This PR uses `GDK_SEAT_CAPABILITY_ALL_POINTING` which includes the touch masks.

So the equivalent would include `GDK_TOUCH_MASK` on `gdk_pointer_grab`.


I would bet on option 2.
