Hello,
I'd like for there to be an available, working examples of autonomous and customized Custom Elements made without use of the class syntax. The Mozilla MDN page for example shows a use of Object.create(HTMLElement.prototype) to create an autonomous custom element on it's Custom Elements page that satisfies this non-class based way of working, however that example doesn't work- it yields Uncaught TypeError: Failed to execute 'define' on 'CustomElementRegistry': The callback provided as parameter 2 is not a function. on customElement.define("my-tag", MyTag).

What is a valid syntax to use now, for creating autonomous and customized Custom Elements? Might we add some examples of such in to the spec?
