When a VM live migration is occuring the source hypervisor's libvirt-exporter errors on querying libvirt

While a live-migration is occuring The monitoring state is locked by remoteDispatchDomainMigratePrepare3Params.

The log below is shown:

Failed to scrape metrics: virError(Code=68, Domain=10, Message='Timed out during operation: cannot acquire state change lock (held by monitor=remoteDispatchDomainMigratePrepare3Params)')

I would expect that when a domain's state is locked due to migration, that the /metrics endpoint would stay available on the host and serve up cached data for that instance and update the remaining domains.
