FrenchGithubUserandGitHub c0357de4ed fix: presence stream stalling intermittently (#20090)
This is a fix for presence updates silently stalling when a `/sync`
request is cancelled mid-write, causing a stream ID to be leaked into
`_unfinished_ids` and permanently pinning the persisted stream position.
