Description

leftshark.tls13.com returns two unknown frames, one with type 0xc, and the other in the experimental range. h2 only produces one UnknownFrameEvent with type 0xc and ignores the experimental range frame entirely. I haven't tracked down the cause yet, and it might be anywhere in the dependency tree.

Research direction

Start by reproducing the behavior against leftshark.tls13.com and compare the two unknown frames, including the frame in the experimental range. Trace HTTP/2 frame handling through h2 and its dependency tree to find where that frame is discarded. Done means h2 produces an UnknownFrameEvent for both frames.
