Yaru: Tiny backdrop issues

[madsrh]

Link button turns orange in backdrop:

I know this was fixed in Yaru 1.0 but checkmark border are dark (in focus):

Same thing here in backdrop:

The first one is fixed upstream, but I forgot to downstream it, while I didn't know the second, nicely spotted thanks

[Feichtmeier]

A little bit embarrassing for me that I probably caused these issues upstream :see_no_evil: :blush:

I think the second one needs a change in _common in treeviews

[clobrano]

I can't reproduce the second issue using master branch. This is how it appears on my machine

which makes sense, since the checks are assets and there is no backdrop version

Closed! All issues are fixed in the master branch
