Comment 4 for bug 1932485

The tests situation was discussed a bit on https://irclogs.ubuntu.com/2021/06/18/%23ubuntu-desktop.html

Basically xdg-desktop-portal tests, once built using libportal, are covering libportal and provided as autopkgtests so they should prevent us from migrating a buggy update.

Would that be enough to address the concern raised in the review?
