Two parts of the definition of Custom Elements conflict:
http://w3c.github.io/webcomponents/spec/custom/#dfn-custom-element-type
"The custom element type identifies a custom element interface and is a
sequence of characters that must match the NCName production, must contain a
U+002D HYPHEN-MINUS character, and must not contain any uppercase ASCII
letters."
http://w3c.github.io/webcomponents/spec/custom/#dfn-custom-element-constructor
"All custom elements must be constructable with a function object, called
custom element constructor. "
A name defined as containing a dash cannot be parsed as a function name in
JavaScript. Consequently the two definitions above prevent mocking of Custom
Elements in a way fully compatible with the standard.
