SUMMARY
When right-clicking a file in Dolphin and selecting Open With, the Choose Application window opens, and the name entry field has some application suggestions if you press its downward arrow icon. In my case, for my test zip file it's offering `org.kde.gwenview`, `org.kde.kate`, `io.mpv.Mpv` and `org.kde.okular`. I want to browse the zip with Gwenview, which is offered as the default selection in the name entry dropdown list, but clicking it does nothing. Selecting something else first (like `org.kde.okular`) and then clicking back to `org.kde.gwenview` now yields a page saying "No matches". Finally, if I enter `gwenview` into the text field, Gwenview is offered and can be used to open the file.

STEPS TO REPRODUCE
1. Have Gwenview installed as a flatpak (optionally not added as an added association for zip files)
2. Right-click any zip with the intention to browse it with Gwenview
3. Select Open With, spawning the Choose Application window
4. Click the downward arrow icon in the text field and select the topmost `org.kde.gwenview`

OBSERVED RESULT
5. Nothing happens and it stays offering to use the default Ark
6. Clicking something else instead of `org.kde.gwenview` in the same list and then back to `org.kde.gwenview` now instead yields a page saying "No matches"
7. Entering `gwenview` in the text field makes it offer Gwenview

EXPECTED RESULT
5. It should resolve `org.kde.gwenview` to Gwenview on the first attempt

SOFTWARE/OS VERSION
Linux/KDE Plasma: Aurora 43 (Universal Blue, image-based)
KDE Plasma Version: 6.5.4
KDE Frameworks Version: 6.21.0
Qt Version: 6.10.1

ADDITIONAL INFORMATION
This is less of an issue if you have added Gwenview as an added association, as it is then offered next to Ark as an icon when the window opens, but even then it still cannot resolve `org.kde.gwenview`.

My distro is image-based and I cannot (easily/robustly) install Dolphin except as a flatpak.
