Re: [w3c/webcomponents] 'attributeChangedCallback' not working with a data attribute on Firefox or Edge (#637)

> On FF 60.5.1 -- 'attributeChangedCallback' callback on a custom component never fires for observed attrbs. I understand the polyfill fixes this, no?

If it works on other browsers, it likely is a bug in Firefox. Please file a bug on https://bugzilla.mozilla.org/

This is not an appropriate forum to report bugs in specific Web browser engine implementation (e.g. any bug in WebKit, Blink, or Gecko), nor is an appropriate forum to inquire questions about a specific JS library or a polyfill. Such questions should be directed towards Web browser engine implementors and JS library / polyfill authors & maintainers.
