Before this MR, reloading the view would not update the expandable status of folders which recently become non-empty.
Steps to reproduce -
- Create an empty folder
- create an empty new file as a sibling (not child) of this new empty folder
- move the new file into the above empty folder
- reload the view
Ideally after the 4th step the previously empty folder should now show an expander adjacent to it but it does not. With this MR it will.
