Saving a content view from the Results tab shouldn't make the Query filter content invisible

Steps to reproduce:

1. Create a new content view.
2. Leave the Query filter as is.
3. Click on the Results tab.
4. Click on Save.
5. Click on the Query & form tab.
   -> The Query filter looks empty. Trying to select some content inside it shows it's not empty.
6. In the Query filter text area, press Enter.
   -> The query filter is visible again.
