@bradfitz requested issue #34387 to be considered for backport to the next 1.13 minor release.

@gopherbot, please backport to Go 1.13.

(I'm assuming.)

In #34387 (comment), @fraenkel notes:

It's a regression. It is a bit difficult to come up with a good set of tests to cover the connection management between the http and http2 side.

@fraenkel, if you would like this to be backported, please send a cherry-pick CL per https://github.com/golang/go/wiki/MinorReleases#making-cherry-pick-cls.

(On the other hand, if you don't think it's a good backport candidate after all, please let us know or close this issue.)

Fixes #34498
