[Feature Request] hover.expandClass

Currently when hovering a function to see the params, if an param is an alias, its possible values are shown as a part of the param description.

Would it be possible to have something similar for classes, where if a class is used as an param, the param description could show the extended class definition (possibly showing extended nested arguments if applicable)?

No files or tests are named. Start by tracing the existing hover behavior that expands alias parameter values, then compare it with the requested class screenshots. Done means a class used as a parameter shows its extended class definition, including nested arguments where applicable.
