KickOff with an empty right view

SUMMARY
Refreshing KickOff's application list twice without changing the category empties the right view

STEPS TO REPRODUCE
1. open KickOff and keep it open (inside plasmoidviewer or add it to the desktop)
2. update the application list twice without changing the category (in my testing I removed and readded the same icon to ~/.local/share/applications, waiting for Kwin to refresh the application list in between)

OBSERVED RESULT
KickOff's right view just goes empty, changing categories fixes it however

EXPECTED RESULT
KickOff should just update the view, adding/removing the icons regardless of how many refreshes there are in the application list

SOFTWARE/OS VERSIONS
Operating System: Arch Linux
KDE Plasma Version: 5.21.0
KDE Frameworks Version: 5.79.0
Qt Version: 5.15.2

Seems like the same root cause as Bug 433119.
