However, you can get an expanded dialog by clicking on the little arrow to the right of the Where box.  Using that dialog allows one to select any folder and displays folder contents.

Can it be a problem with the underlying Tk version? If so, it would be 
helpful to isolate the Tk call and convert it to an equivalent Tcl 
script for the core developers to test.

Fairly recently, Tk has got many bugfixes because of changes in OSX. 
Here is the file that implements the file dialogs:

and the history:

As you can see, it has been touched two days ago (!) to restore some 
window behaviour, which was switched of because of Catalina last August
