Subject: [PATCH] HTML API: Support PARAM, SOURCE, and TRACK tags.

Adds support for the following HTML elements to the HTML Processor:

 - PARAM, SOURCE, TRACK

Previously these elements were not supported and the HTML Processor would bail when encountering them. Now, with this patch applied, it will proceed to parse an HTML document when encountering those tags.

Props jonsurrell, dmsnell
Fixes #60283
