AsType fails for polymorphic lookup fields #55
Description
Running the code from https://github.com/microsoft/power-fx-host-samples/blob/main/Samples/Dataverse101/Program.cs but changing the formula to:
AsType(First(Accounts).Owner, Users).'Full Name'
As described in the docs. this should cast the polymorphic Owner type to a user and return the name of that user. Instead it returns an ErrorValue with a message of "Runtime type mismatch".
