<pre>Don't keep all newly created potential custom elements alive when the feature is disabled
https://bugs.webkit.org/show_bug.cgi?id=159113
Reviewed by Daniel Bates.
Don't keep all HTML unknown elements which has a valid custom element alive when the feature is turned off.
Ideally we want to conform to the behavior in the Custom Elements specification and only upgrade an element
that is inserted into the document. We'll implement that later.
