Recent docs menu bug (reproducible)

[Tridens92]

Here's what I assume is a bug:

1. Press hamburger / menu button to bring up recently used docs list
2. Select a document
3. Exit out of document
4. You are returned out of the document, but the recent files menu is still open. The menu should be closed.

Thanks again for a fantastic tool, @ddvk !

Here's another place where this issue occurs and is a real problem.

1. Go into existing notebook, go to thumbnail view, select one or more pages
2. Chose Move, then Move Out
3. Sometimes the Recent Files list pops up, obscuring the folder list.
