Peristent overlay after file operation in Medley Online File Manager

[pamoroso]

Describe the bug In the noVNC File Manager of Medley Online, after carrying out a file operation that displays a dialog, the partially transparent gray overlay displayed when the dialog is open persists on the page after the completion of the operation. This happens with operations such as uploading or deleting files.

The page is otherwise fully functional and file operations can still be carried out. Reloading the page makes the overlay disappear.

The issue occurs also in an incognito window.

To Reproduce Steps to reproduce the behavior:

1. sign into your Interlisp Online account
2. under Initial Exec, select Interlisp
3. click Run Medley
4. from the noVNC menu, open the File Manager
5. upload a file

Expected behavior The page preserves its color scheme and no overlay is displayed.
