how to reproduce the issue

SUMMARY  
I have two plugins: "Windows" and "Applications". "Windows" is set to be ordered first in Plasma search plugins, and "Applications" is second. In the Application launcher, when typing the names of different currently running applications, sometimes the first search section is a currently running window, but other times it is the application launcher itself. I was unable to find a pattern causing this behavior, but it seems the ordering feature is not working correctly.

STEPS TO REPRODUCE  
1. Set the "Windows" search plugin in the "Plasma Search" settings menu to the first place and mark it as "Favorite".
2. Set the "Applications" search plugin to the second place and also mark it as "Favorite".
3. Type the names of different currently running applications in the search.

OBSERVED RESULT  
The order of the search results varies each time.

EXPECTED RESULT  
The first section should always be "Windows" with a list of currently running windows, and the second should be "Applications".
