I have to go now but will try to look into this tomorrow. CC-ed bholley because of the compartment mismatched error.

Apologies in advance if this double posts (I already submitted this once, but it never showed up here. Given how my day's been going, the original post will appear after I re-submit it...)


Anyway, the first time I see this is in this push: https://tbpl.mozilla.org/?noignore=1&jobname=jetpack&rev=82b6c5885345
