Issue https://github.com/ros/ros_comm/issues/1545 was fixed in ROS melodic, but not noetic.

The fix for the issue took a rather meandering rout to getting in, but PR https://github.com/ros/ros_comm/pull/1684 and PR https://github.com/ros/ros_comm/pull/2014 both seem related.

As far as I can tell, the offending functions in noetic are the same as in melodic pre fix, so this might be as easy as cherry picking those changes over.
