Expected Behavior

Given:

flatpak run --command=bash org.freedesktop.Sdk//24.08 
$ echo "banana" > /tmp/myfile.text
$ xdg-open /tmp/myfile.text 

(note here I tried to make a simplest common example, this comes from the debugging from another tool. Also same behaviour happens when using QDesktopServices::openUrl, which has a similar functionality to xdg-open)

I'd expect the file to get open, much like if I do the xdg-open on something in /usr or /app or a host path.

The file is indeed available on the host:

$ ls /run/user/1000/.flatpak/org.freedesktop.Sdk/tmp/
myfile.text

Current Behavior

The portal silently rejects the process, only leaving this debug line.

(/usr/lib/xdg-desktop-portal:156325): xdg-desktop-portal-DEBUG: 03:45:39.777: Rejecting open request: stat /tmp/myfile.text: No such file or directory

Steps to Reproduce

As explained in the expected behaviour
