This isn't working correctly as UFM isn't rendered.

This isn't working correctly as UFM isn't rendered.

I can confirm that UFM isn't working properly when inline editing is activated. Tested with a property with the alias "headline":
{=headline} was rendered in Blocklist as {=headline}.

And live editing mode seems also not to be working (no matter if inline editing is activated or not).

I also confirm that UFM isn't working.
Should this issue be reopened or is there another already another issue for this?
