As noted in Slack:

The culprit here is localStorage and sessionStorage throwing when touched

and

(i) un-bust chromium’s odd solution to throw when touching window.{local,session}Storage (instead of just leaving it undefined, for feature detection) and
(ii) mock those endpoints out with similar looking, in-memory storage Storage-likes

and

the way more trick, but middle term solution is to do dual keyed storage, and then re-enable these again, but thats going to take some signifigant plumbing
