Problem

TypeScript Intellisense not updating in <script> section of .vue files for referencing other .ts files.
See https://stackoverflow.com/questions/46988578/intellisense-not-working-for-vue-files for example.

Reproducible Case

Create a Test.ts file:

export default class Test {

}

2. In your .vue file, import this class

<script lang="ts">
import Test from './test';
export default class App extends Vue {
    created() {
        const t = new Test();
    }
}
</script>

3. Add a new method to Test.ts

export default class Test {
   foo() { }
}

4. Try to reference the new function in your .vue file

<script lang="ts">
import Test from './test';
export default class App extends Vue {
    created() {
        const t = new Test();
        t.foo();
    }
}
</script>

You will receive an error in VSCode Intellisense saying Property 'foo' does not exist on type 'Test'.

Closing/reopening the file does not seem to fix this. Only restarting VS Code corrects the error. Webpack is still able to compile the code for me, so the error issue seems to be either with VS Code or with Vetur.

Thanks, I looked through other issues a few times, I don't know how I missed that.
