Any additional comments?
I initially thought this issue was a problem with PrimeVue and raised an issue there, but after narrowing it down further it seems more like a core vue problem.
Sounds to me that this could be somehow related to https://github.com/vuejs/core/issues/7086
Basically, in place of a after SSR it tries to render another set of elements, but the template tag does not really have a tag, so parent is null or undefined.
It could be similar behaviour with transition?
a note here: the root cause is that the suspense resolves before the fallback node is mounted. This caused component B to be unmounted twice, causing this issue when it was unmounted the second time.
