Well, this is the one page that I only ever edit in HTML mode (which is why I was so bewildered by the glitch that started this mess). Where I have things like Interactive Diagrams, I'm happy to enter in HTML mode, then press the Source button (to turn it off) and edit that section in WYSIWIG mode without disturbing the ID. It's just one extra click, nice and simple, and it keeps the chainsaw out of the beehive.
