skipSelf behavior differs from rollup

[ef4]

Describe the bug

Rollup and Vite disagree on the precise semantics of the skipSelf option to this.resolve().

The Rollup docs say:

If you pass skipSelf: true, then the resolveId hook of the plugin from which this.resolve is called will be skipped when resolving. When other plugins themselves also call this.resolve in their resolveId hooks with the exact same source and importer while handling the original this.resolve call, then the resolveId hook of the original plugin will be skipped for those calls as well.

And that is the behavior we observe when using vite preview.

But in vite dev, skipSelf causes a plugin to be skipped during all recursive calls to this.resolve(), even when the source and importer are different.
