The problem appears to be this change, which interferes with how @ProvideReactive/@InjectReactive decorators work (nested __reactiveInject__ object).

Since vue-property-decorator is now deprecated and Vue 2 support is ending soon I'm not sure how feasible the fix would be. For now we're sticking with 2.7.13 before we can migrate to Vue 3.
