Describe the bug

We unravelled a bug recently in our application with HMR. When we change a single .vue file it throws an error like this one:

This sounds like a circular dependency bug so we started trying to find it... but after some investigation we noticed this error message only shows up in vite@2.0.0-beta.34 and later.
This commit is the one we are looking at:
ca8442c

Here's are two videos:

1. showing what's happening on 2.0.0-beta.33: everything works correctly, the change is update live and does not throw any error

2. showing what's happening on 2.0.0-beta.34: here the whole importer chain is invalidated.

Not only it throws an error, but it seems inefficient to invalidate the whole chain just to propagate one change on a component.

We didn't notice the bug until today despite running latest vite (2.3.6) because the error is thrown only on this component. I guess because it has a specific set of importers/deps that are not playing well with this whole invalidation process.

Thanks

Reproduction

Right now, this is very difficult to provide a minimal repro, because the bug is probably only showing up at scale. Waiting for your feedback before doing anything.
