Details

ScriptedDirectProxyHandler needs an objectClassIs trap to fix this.  (It actually needs one to handle revoked proxies correctly, independent of this issue.)
Jeff: A DXR link and and a general outline of the fix turns this in to a great first bug.

This bug should await TC39 discussing the spec issue next week.

es-discuss went ahead and made this into a more full-blown thing with property-gets, a canonical symbol, and a bit more.  It's all rather more than seems to fit a mentored bug, at this point.  (Tho it'd work fine for someone half a dozen patches into SpiderMonkey development, far enough to have a sense of SpiderMonkey idioms and such.)
