scopedSlots as Function returns only first element from array: res[0]

[voskresla]

Subject of the issue

We can't use code like this:

wrapper = mount(Tag, {
	scopedSlots: {
		myScoped() {
			return [
				<div id="v-slot">Click in this must return 0 in console</div>,
				<div id="v-slot">Click in this must return 1 in console</div>
			]
		}
	}
})

Steps to reproduce

https://gitlab.com/vskrsl/vtu-issue-scopedslots-array

I try to describe more about use case in test file. And example in native vue (instead tsx) how i can solve this.

Expected behaviour

I expected that all slots will be rendered not only first.

Actual behaviour

Because we have check on string https://github.com/vuejs/vue-test-utils/blob/dev/packages/create-instance/create-scoped-slots.js#L126 we got only first element of scopedSlots array (res[0])

Possible Solution

Does we realy still need this check for return result ? If i delete this check and will always return return res all internal VTU test passed.

Hi!

Looks like these lines were added in a PR to close this issue a couple of years ago. Could you check if you find anything relevant in the discussion there? Otherwise I think it make sense to remove this check as long as no internal tests fail (we might be missing some, so it would be wise to check if the tests in the PR covered all cases).

Thanks!
