x/net/http2: connection-level flow control not returned if stream errors, causes server hang [1.14 backport] #41386
Description
@ianlancetaylor requested issue #40423 to be considered for backport to the next 1.14 minor release.
@gopherbot Please open backport issues.
This problem can reportedly cause an HTTP/2 connection to hang. There doesn't seem to be any reasonable workaround.
