type: Added Element type to ref BailTypes

[kedrzu]

Suppose I want to return ref to the template to be filled with my html element:
const element = ref<HTMLElement>(null);

Then I wrap it with reactive:

const state = reactive({
    element,
    ...someOtherProps
})

Element goes through UnwrapRef and its type inference is broken.

@ktsn I think this makes sense, need a second opinion though.

It makes sense to me as well.
