Reusing nodes should not retain the class list
See original GitHub issue(Originally created in preact-compat as https://github.com/developit/preact-compat/issues/365. See that issue for link to possible culprit.)
In 8.1.0 with preact-compat@3.15.0, it appears that render reuses the first child of the target node and its class list? But only when the first element of the react component tree does not have a class list?
Simply applying className="" to the first element of the top-level React component solves the error, but should probably not be necessary?
This can cause some weird styling due to unexpected CSS inheritance.

Fixed in #677.
yup. right now preact does not remove DOM attributes it does’t have replacement values for when performing an initial render. If anyone wants to PR adding the diff back in that’d be awesome, otherwise I’ll try to get to that as soon as I can.
