Add Screener test for Chat for V2 themes

[Hirse]

The V2 themes add a few new overrides for the Chat Components.
To prevent them regressing for those themes, this PR adds screener tests with the v2 themes.

Also adds a hover-step for compact chat to test interaction.

I didn't add one before as there are no visible changes to any users, not even for documentation.

If you'd still like me to add one, what section would this kind of change fall under?
