Looks good, but let's remove the VRTs here since they are testing something quite generic so they don't add much.

Let's remove these VRTs; they aren't adding much since these styles are already tested elsewhere, and our VRT suite is quite large.

I removed all VRT's initially except for ready and view only ready states, as these are still specific to this widget which uses a bit different options than regular metric, and it will useful to have at least that state, so if something get's broken in the future it is easy to spot.

I think we can remove all the VRTs in this file, as mentioned below 🙂
