The change was made to GTK 3, as Firefox is still a GTK 2 app this issue will remain until the port to GTK3 is finished. I will add the firefox port bug to this bug report.
Also the fix does not expand the file type extensions when the drop down list is selected I have reported this upstream here: https://bugzilla.gnome.org/show_bug.cgi?id=671235
