Given that this seems to fix a severe bug, we could consider to backport 
it to 5.12 with a conditional building if frameworks 5.45 is found. It's 
something we haven't done so far, but given that we face the issue of 
Wayland protocol incompatibilities more often recently, I think it's 
something we will have to do for other protocols as well.
