Comment 6 for bug 1705766

> ...IMO it seems a bit of a waste of effort backporting this specific fix, without also backporting the critical fixes from 4.0.0 alpha 3 and later, which in turn would be best done by going straight to 4.0.0 release (or 4.0.4+)

As I said, I'd be happy to consider either approach. I think it's up to whoever volunteers to do the work to decide which is easier.
