> > @yuki3 Is it possible to make the `[[Set]]` ignored? Currently it is an interop issue: Firefox throws (it should't since no `"use strict"` there, but ok), while Chrome creates expando `foo` property that shadows `<form name=foo>`.

I've landed a fix.  Chromium (tip of tree) is fixed.  Canary (nightly) version containing the fix will be shipped in a day or two.
