Nice! This might be something we want to fix (by default, at least) in the ContextMenu project?

@BasThomas I thought about it. And although I haven’t looked at it enough, I believe that if the background color of the collection view is set outside of ContextMenu, then it should be “together” with the style. Does it make sense?

You’re right, I missed that. Sorry!
