hover types fails with type alias

[andyczerwonka]

Describe the bug

If I have a type alias, e.g.

type SessionEitherT[T] = EitherT[Future, SessionError, T]

and I have a method that returns that type alias

  private def loadCachedReadyPredictor(
      predictorId: PredictorId,
      version: EntityVersionInput,
      predictorClient: PredictorClient,
      acl: AccessControlSession,
      ctx: OrionContext
  ): SessionEitherT[LoadedPredictor] = { ...

if I use that method is a for comp, e.g.

val result = for {
      loadedPredictor <- loadCachedReadyPredictor(predictorId, version, predictorClient, acl, ctx)
...

Hovering over loadedPredictor does not show the type. If I change the return value to not use the type alias, it works.

Expected behavior

I expect the hover to work in all cases

Are you able to reproduce it on a self-contained example? I tried doing more or less what you have in the example and it seems to work for me.
