Bug 503463

SUMMARY
i have Ungoogled-Chromium Flatpak installed. I'm running several browser profiles with different browser user directories: 
--user-data-dir= 
--profile-directory=

After a recent update and Flatpak update, except for Ungoogled-Chromium, I noticed a strange behavior:

Every time I launch different browser profiles, `systemsettings` is launched also on the keyboard shortcuts page for Ungoogled-Chromium and the keyboard shortcuts of the installed browser extensions are set there, but since I have different profiles with different installed extensions and keyboard shortcuts - every time I launch different profiles - every time the keyboard shortcuts in `systemsettings` are different too.

The xdg portal is involved somehow i guess.


STEPS TO REPRODUCE
1. Run Ungoogled-Chromium Flatpak with different flags: `--user-data-dir=/tmp/custom1` `--profile-directory=Custom1`
2. 
3. 

OBSERVED RESULT
`systemsettings` starts each browser start

EXPECTED RESULT
`systemsettings` shouldn't start each time the browser starts
