I don't think this is the case, afaik when server provides a intermediate that points to a distrusted root, the verification fails and no further attempts are made.
The reason this works on firefox, is that Mozilla added a cross-signed intermediate certificate directly to firefox that replaces the server on see(its quiet possible that for chrome it is the same situation). https://fkrenzel.cz/posts/2025-root-ca-mess.html#firefox
