Libreoffice 6.2 snap should use Yaru-dark for its interface when it's used systemwide.

Libreoffice 6.2 snap falls back to Adwaita theme.

Libreoffice 6.2 snap with Yaru works as expected.
Libreoffice 6.2 deb with Yaru-dark works as expected.
snap install libreoffice)git describe: r29-45-g065dd123
Software that presents the issue:
The right place to file this issue is https://gitlab.gnome.org/Community/Ubuntu/gtk-common-themes/issues (the glue snap-packaged applications use to render with GTK themes; it doesn鈥檛 seem to include Yaru Dark yet). This isn鈥檛 an issue with the codebase of Yaru proper.
@jhenstridge does this make sense to you? Is there something we can do to help?
@clobrano: the gtk-common-themes snap is explicitly not including Yaru-dark, likely because the debian packaging used to exclude it too. We just haven't gotten around to syncing up.
I've put together MR !13, which should help. It'll need to be merged and a new build published to stable before this is properly resolved.
A test snap is available here:

sorry for not testing this @jhenstridge. In my VM 18.04 the dark variant is even more broken than this for libreoffice (transparent menus and no style at all), I am not sure why, but this prevent me to test the link above
And now I'm late

It is fixed now, thanks!
