fixes #13029
This prevents the inflater/deflater from holding a reference to the frames buffer when it is fully consumed and awaiting the next frame/message.
I could not find a way to write a test case for this, but tested manually by accessing the
DeflaterPool, getting theDeflaterused by the websocket session, and using reflection to view its internal buffer.
