Comment 22 for bug 1970594

I am testing in a fully up-to-date Kubuntu 22.04 VM:

    $ xdg-settings check default-web-browser firefox_firefox.desktop
    /usr/bin/xdg-settings: 734: [: x!: unexpected operator
    yes

    $ echo $?
    0

So while the error printed on stderr is misleading, the result printed on stdout is correct, and so is the return code.

I am still going to SRU the updated patch to jammy, as I think it's useful, but it shouldn't impact firefox's checking whether it is the default browser.
