--- Comment #1 from Michael Catanzaro <mcatanzaro at gnome.org> ---
The Wayland protocol documentation does not indicate when
wl_data_offer::receive requests can be sent, nor when wl_data_source::send
events will be received. Some clients may assume that data may be sent only
once for a single MIME type during a DnD session (which GTK+ does to work
around bug #91944). Other clients may be prepared to handle multiple
simultaneous data transfers (when dl_data_offer::receive is called several
times in a row, perhaps in a loop), while yet others may be prepared to handle
multiple data transfers only if one is ongoing at a time.

The protocol should provide some indication of what well-behaved clients should
be expected to support.
