TryBot is sometimes running into deadlocks on js/wasm. We haven't been able to reproduce them yet. This workaround is an experiment to resolve these deadlocks by retrying a missed timeout event. A timeout event is scheduled by Go to be woken by JavaScript after a certain amount of time. The checkTimeouts function then checks which notes to wake by comparing their deadline to nanotime. If this check fails erroneously then the note may stay asleep forever, causing a deadlock. This may or may not be the reason of the observed deadlocks. Updates #28975.
