Looks like there is a rh-context-provider in that panel that was missed during the rh-context-provider -> rh-surface transition. I can remove it. I don't think we would want someone combining a dark tab and a light panel thoughts @coreyvickery @marionnegp?

If we allow mixing:

@zeroedin Correct, no mixing.
