Files no longer opening in their open project

[Allen Hancock]

I just upgraded to BBEdit 16 (woot)

and I made another change at the same time, so I'm not sure if either are related

I enabled this expert preference from

https://www.barebones.com/support/bbedit/ExpertPreferences.html#proj

BBEdit will not automatically reveal documents in the project list when you select them; View => Reveal in Project List works for this purpose. If you want automatic revealing:

defaults write com.barebones.bbedit AutoRevealSelectedDocumentInProjectList -bool YES

Now, if I have a project open and use another app or the finder to open a file in the project, the file opens in its own window, instead of opening in the context of the project as I'm used to

(I've always run BBEdit with AutoRevealSelectedDocumentInProjectList TRUE, it's just that I got a new computer a few weeks ago and never re-enabled it til now)

Is there something I can do so that a Project's file will open in the Project again?

Thank you!
