It has low hit count, but it is a relaibility problem, a regression in 8.0 and low risk change -- we should consider to take it. Let's do bar check with Tactics. |

Backport of #99889 to release/8.0-staging
Fixes #98945
/cc @MihaZupan
Customer Impact
Reported by a customer in #98945.
It is a deadlock that can happen in a race when the server closes an HTTP/2 connection (which is not that common for HTTP/2).
Regression
Yes, introduced in 8.0 (likely in PR #90094).
Testing
Tested with a custom build of Libraries which introduces delays increasing the chances of the problem happening.
Risk
Low
