Small issue with Rider and detached windows #712
Description
I'm using ANTLR Preview with Rider (on Windows if that matters) and noticed an edge case.
Open a .g4 file within Rider and detach it (I moved it to my other monitor).
Close Rider.
Open Rider - the previous state should be restored (.g4 file detached from IDE). Right click on rule and select "Test rule condition".
ANTLR Previw will open in tool window within IDE but it will be disabled. And it will stay disabled until:
a) A .g4 file is open in IDE (not detached)
b) Detached .g4 file is moved to IDE
c) ANTLR Preview tool window is moved to detached .g4 file.
Not a big deal once you know how to workaround it.
