See also:

The masquerades-as-undefined approach works equally well on such  
sites, and it works better in theory, except for the nastiness of  
violating ECMA-262 rules, which matters not only for conformance

that make it a chore to support masquerades-as-undefined.

Anyway, I wanted to cite the bugzilla links for anyone interested in
