I've added you to an existing development ticket for this bug.
There is some good news regarding this bug: tags in the web UI (and
the top-level record for the ticket) still contain the tags, and
subsequent UI updates will include those tags until they're
changed. Even subsequent API updates should not actually destroy
tags until they're overridden.
Internally, what's happening is the latest "version" record for
this ticket is not getting the tags value set on it, so the "diffs"
between versions show that tags were removed even though they
remain on the ticket.
To summarize: The "tags cleared" message is mostly a display
error, and subsequent updates should still have the tags in place
in the UI.
We'll update this discussion when we have more information to
share on the fix.
