I think this worth merging and pretty safe.

Merge approved for 58, assuming this is ARC++ specific.

The description does not really say the problem this solves though, so I am not clear this should block a stable release.

Yeah, it wasn't clear sorry. The shadow for active/inactive window should change, but ARC window was always using the same MEDIUM window.

Your change meets the bar and is auto-approved for M59. Please go ahead and merge the CL to branch 3071 manually. Please contact milestone owner if you have questions.
