OK. I'll change it to 1.

Sure, I get that. But my question was more about adding a property that
"breaks" existing content. That's the position we're in. We didn't
support the properties before now, and we can't use the initial value
without introducing regressions.

It's not a big deal, just a minor annoyance. Technically we won't
comply with the specification.
