and
https://labs.w3.org/spec-generator/?type=respec&url=https://w3c.github.io/screen-orientation/index.html?specStatus=WD&shortName=screen-orientation#type-attribute-get-current-orientation
don't produce the same results.

The first one contains broken links represented by red squiggles, eg. section 3.3

I wonder if it's some kind of weird mixed content thing... maybe we should ban http for the service? there really shouldn't be any reason to be using it nowadays.
