types When using `use_parent_field_for_type` option in `polymorphic_embeds_one`, the `action_and_struct/4` function's cond block was missing a clause to handle the case when both `type_from_parent_field` and `type_from_map` are present and match. The existing cond only handled: 1. type_from_parent_field is nil -> :type_not_found 2. type_from_map is nil -> get module and return action/struct 3. types don't match -> raise error This caused a CondClauseError when form params included the `__type__` field matching the parent field type (e.g., during form validation). Added a `true` clause to handle the matching types case, which behaves the same as when type_from_map is nil - it uses the parent field type to determine the module and returns the appropriate action/struct tuple.
