The entire page
What information was incorrect, unhelpful, or incomplete?
The docs talk about font fallback and make it sound like font-size-adjust applies only to fallback font:
ex-height
Uses the ratio of x-height (height of lowercase "x" in a font) to font size (aspect value) to adjust the fallback font size.
As far as I understand, this is incorrect. font-size-adjust applies to any font, fallback or not. font fallback is completely unrelated here. It just one motivation to use the feature, but there are others. For example, I might want to normalize x-height between normal font and monospaced font for code snippets.
What did you expect to see?
Docs do not incorrectly state that font-size-adjust kicks in only for fallback fonts.
Docs provide other motivation for usage besides font fallback.
