1881851 - Toolbarbuttons should have a visible border in prefers-contrast/forced-colors

Status: NEW

(Firefox :: Theme, defect, P2)

Description

[Mark Striemer [:mstriemer]]

Our button specs for forced-colors mode depend on buttons having a border since in Windows default HCM themes the ButtonFace and Canvas colours are quite similar. The border is required to provide correct contrast.

Update the toolbarbutton styles to include a border (or potentially an outline) so that they can use our HCM styling.
