GRPC StatusRuntimeException metadata on client side is empty

[ashalak-kaseya]

Describe the bug

During GRPC communication on server's side I throw StatusRuntimeException with some custom trailers, meaning metadata with some special keys with values.

After triggering the request I see that the client's side "onClose" trailers are empty, but headers contain my data instead.
So without custom interceptor for GRPC client below I cannot get my data from StatusRuntimeException's trailers (using exc.getTrailers()):

Expected behavior

On client's side trailers inside StatusRuntimeException have to contain trailers are added on server side.

Actual behavior

On client's side trailers inside StatusRuntimeException are empty, but instead that headers contain trailers are added on server side.
