Will the attributes and listeners still be applied to that created tag? Did you test that?

[jlangy]

I tested the tag and the slot content, good point though I will extend the testing to make sure any attributes and listeners come through

[jlangy]

I added some tests for that (linted the pagestepper too), it's using some vue magic with fallthrough attributes which looks odd, I put in the comment to the docs explaining why it works though.

The reason I switched from createElement is it changed to a global import (instead of the first arg to the render function) in vue-3, which was causing issues related to vue being imported twice with jest and storybook.

Looks good.
