Again, a very tiny issue: Context menu checkboxes are black but gray on hover.

Adwaita is also a mixing black and white borders, so perhaps this should/could be fixed upstream? I'm not sure what they are going for here, but IMO the border should be the same color as the text.

They should look differnt in master, like this:

Better an outdated issue than no issue tracked for the LTS :)
