UE 4.25.1 editor bug: Closing "Find in Blueprints" dialog hangs editor

When doing a “find in blueprints” action, double-clicking to go to a hit, and then closing the window, the editor hangs and must be killed in task manager.
This is quite repeatable for me.
Connecting with the debugger and looking at the stack trace, it seems to be hung waiting for some worker thread to finish, but it’s either already finished, or it’s in turn blocked, presumably waiting on the editor and deadlocking.
