Why would there be an address change in a handover? That is definitely not

Why do you believe that address changes in handover? It's an integral part
of 3GPP standard that your existing bearer is used for handover, so your
address shouldn't change. If it changes then it means the handover didn't
work as designed, probably due to some radio related problem. If the
address changed, then it means the bearer was torn down and a new bearer
was initiated. This is definitely not expected behaviour. We have plenty
of customers with bearers that are up for tens of days in a row.

If a user is accessing a stream from an IPv6 enabled CDN that stream
shouldn't be reset just because a handover happened.
