ScriptedDirectProxyHandler needs an objectClassIs trap to fix this. (It actually needs one to handle revoked proxies correctly, independent of this issue.)

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.)
