Child component having v-once and a property binding with v-bind does not react to changes to the bound property

Hi, is there an workaround for the following scenario:

the parent renders a child and specifies v-once
the child has
when the parentProp changes the child binding does not update.
This seem to be related to v-once directive as the watcher for parentProp runs in parent.

Is there a workaround in this scenario?

Thanks
