Considering that manual VM LIVE migrations via CloudStack from non-dedicated to dedicated SHOULD/DOES work - then I would say this is an "unhandled" case, which indeed should be handled and live migration should happen instead of stopping the VMs.
I assume someone else might jump in - but if not, please raise GitHub issues as a bug report.
