Masakazu Kitajo commented on TS-3822:
-------------------------------------
Strictly speaking, we need to find a stream to check if the stream is open
state, and then return other error. The case happens when endpoint sends
HEADERS frame w/o END_STREAM flag more than once on the same stream.
However, the change is reasonable for 6.0.0. The case above should be care with
a h2spec testcase.
