This bugfix is not able to be backported to 6.4.z and will be resolved in 6.5 which is nearing completion. We are going to close this out and can track this in the main bug https://bugzilla.redhat.com/show_bug.cgi?id=1669241 If anyone feels we need to extend extra effort to rework a backport of this, feel free to re-open with a justification.
