You don't seem to be using shadow DOM at all i.e. there's no calls to attachShadow in your code. – Robert Longson Mar 15 '22 at 14:02

@RobertLongson Yes, I am not using them in the snippets pasted in the question. My query was more on the lines of what it mentions regarding the limitation. I think your suggestion seems to indicate that they are referring to the _encapsulation of style_ which won't be possible in a Standard DOM but is possible in a shadow DOM. I guess _that_ is the limitation. – Zoso Mar 15 '22 at 14:06

You're right, afaict. Raw templates (forget components) seem like an easy way to encapsulate chunks of UI combined with their own – Ron Burk Sep 05 '22 at 22:52
