I should point out that this is e10s only.

Comment 2

[Tracy Walker [:tracy]]

Also notice, if you select "Groups" the select button displays "Group 1" and Groups is checked.  You can't even select "Groups" in non-e10s.

Attachment: Use tagName converted to uppercase

HTML nodes return their tag name in lowercase.
