Script styles in fullscreen when not in script mode

I’m probably using the wrong terms, as I don’t use script writing mode at all, but I’ve noticed that when in full screen if I hit Shift-Cmd-Y it brings up a script formatting popup with active functionality. (Has Scene Heading, Action etc in it)

As these options in the menu are greyed out for me, I’m guessing this popup shouldn’t be available when in full screen mode? It’s not available outside of full screen.

Did I find a bug?

Oops, yes, that is indeed a bug. I’ve just fixed it for the next update, thanks for bringing it to my attention.
Thanks and all the best,
