I did not mean to remove the regression label. Seems to be a race in Jira. I just added labels. It seems my hs-tier3 label got lost as well when Kim added the hs-tier1 label at the same time :-)

Bumped from 'P4' -> 'P2' and added regression label since existing tests started failing. [~jwilhelm] - Did you mean to remove the 'regression' label or was that a JBS oops because we touch the bug at the same time?
