Currently, kwin will continue matching dnd actions after a drop. This is mainly needed in order to make "ask" action work. However, it appears like there are clients in the wild that update offer actions after receiving wl_data_source.dnd_drop_performed and wl_data_device.drop events. One could argue that's a client bug, and perhaps it is, but the spec is vague about that. In meanwhile, let's make sure that dnd action matching is active after drop only when the selected data source action is "ask."
