CleanEntityStorageAsync() does not clean entities (likely 'transient' ones) #324

Hi! I am migrating some code from from in-process durable framework to isolated model, and I got stuck with handling entities.
I was looking for an option to completely delete entities. Reading docs, I learned that I can use DurableTaskClient.CleanEntityStorageAsync() to clean storage. I manually delete state for entities I wish to query and then I call this method, which does nothing, reporting that it purged exactly 0 entities.
Now my entities in question appear to be 'transient' so that I need to pass new EntityQuery { IncludeTransient = true } to GetAllEntitiesAsync() in order to see them in the output. It feels like by deleting state I promoted entities to transient and now entity storage is not cleaned because of that. The scenario for debugging is roughly the following:

// Here I get two transient entities with no state
var entities = await client.Entities
  .GetAllEntitiesAsync(
      new EntityQuery
      {
          IncludeState = true,
          IncludeTransient = true
      }
  )
  .ToListAsync();

// And here I get 0 removed entities and 0 orphaned locks released
var result = await client.Entities.CleanEntityStorageAsync(
    new CleanEntityStorageRequest
    {
        RemoveEmptyEntities = true,
        ReleaseOrphanedLocks = true
    }
  );

// Here again I get two entities
var entitiesAfter = await client.Entities
  .GetAllEntitiesAsync(
      new EntityQuery
      {
          IncludeState = true,
          IncludeTransient = true
      }
  )
  .ToListAsync();

Perhaps I do not understand something about this flow?

Also, when querying for entities, even though I specify IncludeState = true, resulting metadata do not include state and have IncludesState set to false. Is this how it is supposed to work?

I debug this code locally, backing durable framework by Azurite storage, so I can access and inspect my entities, and check if they are removed or not, or if they have associated state.
