           Summary: [Custom]: Specify preference of localName and

As specified in instantiation of custom elements that "custom tag" will take
preference over "type extension", it is required to specify the same in case of
createElement(...) .

 Element createElement(DOMString localName, DOMString typeExtension);

Here if localName is also a custom tag, then what will be the prototype of
"Element"? Will it be of typeExtension or of localName.

Consider the following case:

var xA = doc.registerElement("x-a");
var xB = doc.registerElement("x-b");

var customElement = doc.createElement("x-a", "x-b");

What should be the prototype of customElement?

AFAIK, this will be the same case as specifying:

<x-a is="x-b"></x-a>

In this case prototype will be of "x-a".

If the above theory is correct, then
web-platform-tests/custom-elements/instantiating-custom-elements/extensions-to-document-interface/create-element-interface-type-is-a-type-extension.html
test case is wrong.

If this issue has been raised earlier, then please provide the link and close
this bug.
