Filter menu doesn't scale as expected on smaller screens

[RubenFricke]

Describe the bug
If the screen is below a certain amount of pixels in height, it does not fully show the filter menu.

To Reproduce

1. Open the project overview page
2. Validate that the bottom of the filter menu is cut off (if you have a smaller screen yourself)
3. Otherwise, you can achieve this by changing the height to 600px (in Chrome you can do this by clicking on F12 -> toggle device toolbar
   
   

Expected behavior
As a user, I would like to be able to see the complete filter menu. I'm not sure what the best practice is, but I think it can be solved by adding a vertical scroll bar.
