When watching from the middle of gameplay, due to a series of failures,
`SpectatorClock` would not get seeked to the current time, causing all
clients to look like they were out of sync.
This is a hotfix for the issue. A better fix will require framework
changes or considerable restructuring.
I'd recommend testing this works in practice and agreeing that while it
is a hack, it's likely not going to cause issues and is something we
want to see fixed sooner rather than later.
