Cannot open link from Flatpak app if the default browser is Flatpak-packaged Chromium #1396

Expected Behavior
Clicking on a link within a Flatpak app should open the link with my default browser. When I have Flatpak Chromium as my default browser, the link should open in that app.
Current Behavior
Clicking on a link inside of a Flatpak app does nothing.
Trying to run xdg-open inside of a Flatpak container produces the following output:
hitomi@machine ~ $ flatpak run --log-session-bus --command=bash us.zoom.Zoom

B291: <- :1.20 return from C14Steps to Reproduce
- Install Chromium through Flatpak.
- Set the Flatpak Chromium as your default browser. Run:
xdg-settings set default-web-browser org.chromium.Chromium.desktop - Open a different Flatpak app and try to open a link. (The link will not open.)
Anything else we should know?
I have tested the following browsers. Links from Flatpak apps do not correctly open with these browsers:
- com.google.Chrome 126.0.6478.126-1
- io.github.ungoogled_software.ungoogled_chromium 126.0.6478.126-1-1
- org.chromium.Chromium 126.0.6478.126
This issue seems to only affect Chromium browsers packaged with Flatpak. I am able to open links with the Flatpak version of Firefox: org.mozilla.firefox 128.0. I also do not have this issue with the distro's www-client/chromium-126.0.6478.126.
Note: My xdg-desktop-portal and pipewire are compiled with the flatpak USE flag.
