File Manager shows files from different folders

[intjftw]

When clicking the back button in the browser, the former content of the File Manager gets "stuck", and shows the current and the former files and directories as well. This is kind of a strange bug, it does not come up every time, and I have experienced it in other use cases as well, although I did not record these occasions. All content that appears in the window works well, anyway.

I could reproduce this bug this way:

1. Open a file in CodeCompass.
2. Open a file in a subfolder (through the File Manager).
3. Press the back button in the browser.

This bug is still valid, I have added this to the Lab tasks.
