Stars druid rules question

[Mitchellnotes]

Random rules question. On my turn, i use my bonus action to activate starry form and then cast polymorph on myself. Do i still get the benefit of starry form?

Starry form has explicit wording in terms of when it ends, however, i believe there are mearls tweets that a polymorphed barbarian loses the benefit of rage. Would my druid lose starry form? I'm guessing that i wouldn't lose haste if it was used on me, would starry form be like that or more like rage?

I believe you would lose the benefits of Starry Form, because you lose all of your class features when you cast Polymorph.
