[Bug] Extension incorrectly returns wrong message when changing from Element to Requirements view when focused

[philljenkins]

Task or scenario I'm trying to do

• Get a list of issues sorted by Requirement for an element/component and all it's children

Steps to reproduce the behavior:

1. Go to any page, such as Altoro Mutual
2. Click on Scan page
3. Select an element, such as main
4. Select "Focus Mode" by selecting that button switcher next to All
5. Notice all the issues listed as usual for main and all the children
6. Select Filter drop-down and click on Requirements
7. Incorrectly clears list of issues and returns unexpected error message that the page hasn't been scanned.
