--- Comment #9 from Dimitri Glazkov <dglazkov@chromium.org> ---
Here's the summary:

Depending on your heritage, you will be instantiated in one of two ways when
using document.createElement/NS or your constructor.

1) If you inherit from an existing HTML or SVG element, you and all your
descendants will always be instantiated with the "is" syntax.

2) If you inherit from HTMLElement or SVGElement, you and your descendants will
always be instantiated with the custom tag syntax.
