@daggertooth @squirrel @bea Is the collapse done on the sender's side, or on the recipient's?
@kellerfuchs @daggertooth @squirrel it's client side, and it probably will never go to mainline as far as i know. it was denied there once already long ago

@bea can i cherrypick it
@squirrel it may be difficult as it's been refactored a bunch of times
i think best might be to wait til the next batch of enhancements to the theming/frontend system are in and then switch over to the fork with the support of the team
