https://tbpl.mozilla.org/php/getParsedLog.php?id=20155828&tree=Mozilla-Inbound Bobby, could you take a look at this?
Flags: needinfo?(bobbyholley+bmo)
Given the stuff that gets leaked here, I might wildly guess that it has something to do with off-main-thread XPCWrappedJS usage. If anything, the leak profile will change when I rip out all that threading goop.

This only occurs on M3 - there must be a specific test triggering this. Have cross referenced between two logs, one old, one new - and on two platforms (fed64/winxp) to make this list of candidates. (Though with the lowish frequency of this bug, retriggering on Try to bisect this list further may still be impractical, not sure).
