Grep results panel displays source code or form designer

[eivindbakkestuen 46]

Having just installed Delphi 12.2, I'm seeing something I've not seen before. I have the grep results panel docked on the right with the project manager etc; somehow it is now displaying content matching the form designer, or the source editor, switching with each F12 press.

 

Anyone else seen anything like this? I'm not sure exactly what I did to trigger it, and it didn't happen again after restarting the IDE.
