HTTP2 session and stream leak

Subsystem

HTTP2

While using HTTP2 server without any reverse proxy I noticed NodeJs process memory constantly increases, switching back to HTTPS and it works ok.
So I keep track of every HTTP2 stream using a WeakRef. After some hours there are so many valid WeakRefs although their destroyed field is true and session is undefined, also each stream has a buffer of 65kb. I have set HTTP2 Server timeout for 2 minutes, but some of streams are for hours before.
Then I kept a WeakRef to session for each stream, and while the session field of stream in undefined but its WeakRef is valid and the derefed session destroyed field is also true. I checked the remote address of the session in ss output and the connection doesn't exist there too.
I think some of sessions are destroyed but not removed from the sessions poll. It also destroy session streams and set its session to undefined but as it has a pointer in session's stream poll it's not garbage collected.
Maybe this is related to #42710
To overcome the memory increase I have to restart the node process every day and I think it's not really usable in this state.

Could you provide a snippet of code to reproduce the problem?
