Comment 17 for bug 1851250

Thanks for testing, and for the feedback Alberto.
Let's say it's okay to assume that the portal is already running and accessible through the bus (i.e. the ListActivatableNames path won't be taken − there's an upstream bug to track this: https://bugs.chromium.org/p/chromium/issues/detail?id=1278336).

Then indeed the problem remains for xenial, bionic and focal where the XDG desktop portal isn't new enough. But it's unlikely that a new major version of the portal can be backported to these release with a regular SRU, so it looks like a "Won't Fix" status to me, what do you think?
