Typing a ComponentPublicInstance Returned from App.mount()

[kirkbaly]

Say that I instantiate a new Vue app with a root component like so:

const componentInstance = createApp(MyComponent).mount(someElement);

Is there a way to get the correct type of componentInstance based on the component MyComponent? Ideally, something like InstanceType<typeof MyComponent>, though that specifically does not work in this case. Or, alternatively, is there a way to access something on the ComponentPublicInstance that could be typed as InstanceType<typeof MyComponent>?
