The bug was marked as affecting webkit2gtk 2.30.6, but the
xdg-desktop-portal-gtk dependency was only added in 2.32.0.

xdg-desktop-portal-gtk was designed for Flatpak as far as I'm aware
but it does not depend on it.

It recommends Pipewire, but you don't need to install it if you don't
want (it does depend on libpipewire, but just the shared library).

The rest of the dependencies pulled by xdg-desktop-portal-gtk are
pretty standard desktop dependencies (gdk-pixbuf, ALSA, fuse, ...).

Exactly.

That's not what happens at the moment, we can revisit this if that's
the case, although I don't see why the portals would depend on
Flatpak.

Not all bugs are obvious, not all bugs happen in all scenarios and not
all bugs are discovered immediately :-)
