Move a preview comment's status
Applies the status only when expected_version equals the current comment lock_version. A stale version returns 409 with the current comment in error.details.preview_comment. Status timestamps are recorded by the server and do not order writes.
A thread that belongs to a work item is not writable workflow here.
This returns 409 with the current comment in
error.details.preview_comment, and the work is changed through the
work item instead. Draining is how a company reaches that state: a
thread a client is still executing is never linked to work. A thread
that belongs to no work behaves exactly as it always has.
