suggest updating this to backtick interpolation while you are here
`New session already forced with device ${sender} ...`
etc
There was a problem hiding this comment.
also suggest new Date(forceNewSessionRetryTime).toUTCString() to make the timestamp readable

Previously, we only marked the time that we re-created an Olm session after the session was created. So if we try to unwedge while we're in the middle of unwedging, it won't be rate-limited, and we end up creating multiple new sessions. This patch sets up rate limiting before any
awaits, with a delay of 5 minutes, so it doesn't race any more.Fixes element-hq/element-web#25716
No tests yet because I'm not sure how to test this. Suggestions welcome.
