I don't see where/how this has been fixed. To me, it's clear that
"foo at bar.com,   bar at bar.com" will now be represented as
"foo at bar.com,bar at bar.com" in the DOM but not "foo at bar.com,
bar at bar.com," (which will be "foo at bar.com,bar at bar.com,"). In addition,
this value seems to still be invalid.

Can you point out the section/line that handle this case?
