This is not a bug.  They are deliberately breaking IPv6 because they
consider this a feature.  You should not try to work around such issues.
It is a fight you cannot win.  Any workaround will only encourage them
to come up with new ways to break IPv6.

Who are "they" and where is this information coming from? And what do
they
gain from breaking IPv6? Wouldn't it be easier for them just to disable IPv6
than adding random looking bugs?
