Re: [polymer-dev] Mixing Polymer and "raw" custom elements

[Erik Arvidsson]

Yes, once you start using the Shadow DOM polyfill all nodes needs to be wrapped by the Shadow DOM polyfill.

Sorry if this post is duplicated, have been having troubles posting questions. If you mix some polymer elements on the same page with other elements created using the raw custom elements polyfill and / or x-tags and / or your own library based just on the custom elements polyfill (basically any implementation of custom elements that doesn't include the shadow dom polyfill), will those elements automatically also get "wrapped" in polymer wrappers because of the presence of the polymers elements on the same page? In other words, will the custom elements.polyfill for say your x-tags components suddenly start using the shadow dom polyfill ?

It's completely true that ShadowDOM Polyfill wraps *all* nodes when it's enabled. This is necessary to keep it (99%) transparent.

But for the record, x-tags or custom-elements will not automatically start using shadow roots. IOW, you don't get shadow dom *encapsulation* unless you ask for it.

If this distinction is confusing to anybody, please follow up.
