Admittedly, we have not been keeping a list of the browsers affected by this behavior.
The fact it was true for a widespread version of Internet Explorer was enough for considering it as a limitation on the library use.
I confirm that the documented behavior occurs on Internet Explorer until version 6,
while it disappears on version 7.

By the way, we will evaluate if the limitation statement can, nowadays, be removed; thank you for the notice.
You may also consider the IE6 case as not important.
