Clear and concise description of the problem

First of all, thanks for the @hover experimental feature, as this is one of the main reasons I'm migrating.
However, I found that seems group-hover: does not support that.
None of group-@hover:, group:@hover:, @group-hover:, @group:hover: works for me.

💚

Suggested solution

group-@hover: or group:@hover:
