Exported functions become "stale" on hot reload

[enyo]

Describe the bug

When a component exposes a function with export const doStuff = () => { /* code */ } so that an outer component can invoke it, the code inside the exported function doesn't have access to the local variables anymore after reload.

@bluwy are you sure it's the same? Mine has nothing to do with context module.

Ah I think you're right. I can reproduce this too at https://stackblitz.com/edit/vitejs-vite-rdqnfu?file=src%2FInner.svelte&terminal=dev. Transferring this over to vite-plugin-svelte as HMR is not related to Svelte. But this issue could be related to svelte-hmr too.

Repro steps with stackblitz:

1. Start the dev server
2. Edit Inner.svelte
3. Click on the "Open" button
4. Notice that the "Open: false" text did not become "Open: true"

i suppose this is one for svelte-hmr. cc @rixo

Yes, I confirm this is independent from the context=module issue, and that this is the responsibility of svelte-hmr. This one should be easier, since it pertains to component instances, where svelte-hmr is really acting.

Should we transfer the issue to svelte-hmr or create another one there?

[bluwy]

I don't have permissions to transfer over to svelte-hmr, unless someone does 👀 Else I'm fine recreating an issue there too.
