Intellisense not working in a monorepo

Description

In the example monorepo, I have a library package and an app package. The library uses vite build --watch and vite-plugin-dts to ensure that builds and types are regenerated as needed. The app simply uses the vite dev server.

If I make changes to packages/components/src/components/Button.vue, then edit packages/app/src/components/App.vue, the changes I made to Button.vue will not be reflected in intellisense while editing App.vue. I must restart VLS in order to see the changes.

I am not 100% certain that this is actually a problem with Volar or not.

Steps to Reproduce

1. Run yarn start:dev in the components and app packages (needs two consoles)
2. Add or remove values to the Variant type in packages/components/src/components/Button.vue
3. Open or continue editing packages/app/components/App.vue
4. Remove the current value from the variant prop and hit ctrl-space

Expected Behavior

The list of available values for the variant prop, reflects the current code of the Button component

Actual Behavior

The list of available values does not change.
