Steps to reproduce

Observe the render result, we can see the second custom element doesn't have tabindex or data-test attribute, they are set on its properties, not attributes

What is expected?

Should have correct attributes

What is actually happening?

I believe this is coming from below in packages\runtime-dom\src\patchProp.ts

// #11081 force set props for possible async custom element
(el as VueElement)._isVueCE &&
(/[A-Z]/.test(key) || !isString(nextValue))

All non-string props with no capitals are set as element's properties
