issue is around meshconfig merging. We somehow end up not applying the changes. Assuming its related to e927c33, although not sure how yet

It looks like the test correctly writes out the mesh config, but istiod is no longer processing. Deadlock? #39864 doesn't find anything though.

There are a ton of mesh config handles, and they are synchronous, so its pretty hard to identify

figured it out... we are using a file mount for external istiod 🤦 those are slow to update unlike configmap watcher
