Oh, this is just telling you that |
If you're using a Shadow DOM polyfill (like Shady DOM) and you're still seeing this error, you need to load the Shadow DOM polyfill first so that it can do its patching before the custom elements polyfill does its own. edit: Additionally, the custom elements polyfill needs to use the Shadow DOM polyfill's methods to inspect / walk the tree. If it doesn't, the custom element polyfill will be operating on the 'composed' tree and callbacks can end up being called on the wrong elements and at the wrong times. |
@puppetmaster3, I'm going to close this since I don't think this is actually a bug. If you find that this still happens in situations where you're using Shadow DOM, please leave a comment and I'll reopen it. |
I get Custom Elements:
Element#attachShadow
was not patched error.Works fine on Chrome.
