`spread()` doesn't use the `children` property when an `Accessor` is passed

[AFatNiBBa]

Describe the bug

The type definition of the spread() function states that it also accepts a function that returns an object instead of the object itself, but here it doesn't check if props is a function when accessing the children property. After checking with the playground, it seems that no property works

Steps to Reproduce the Bug or Issue

Just look at the output:

• "This works" is visible
• "This doesn't" should be visible but isn't

Expected behavior

It should get the properties from the returned object if props is a function OR the type definition should be made to match the actual behaviour by disallowing Accessors
