Nextcloud Office: Web browser's back arrow doesn't work, blank screen

Describe the bug

reported by Julie

When I click on the web browser's arrow to go back one step (i.e. out of the spreadsheet and back to the original folder I entered) it doesn't always respond and I have to repeat the action another 1 or 2 times before I can "escape" the spreadsheet.

To Reproduce
Steps to reproduce the behavior:

1. Open a spreadsheet
2. Click the web browser's back button
3. Sometimes nothing happens, just a blank screen
4. I need to click multiple times (URL in the address bar changes but nothing happens) until I'm back to NC BUT not the place I was expecting to: Dashboard

Additional notes from Pedro: it seems the document is correctly closed, but the user gets stuck in a blank screen:

Expected behavior
Click arrow to go back should get me back to the previous screen that I was in before opening the spreadsheet.
