Re: [csswg-drafts] [css-fonts-4] Avoid font synthesis outside of variable range (#7999)

> User agents that implement synthetic bolding and obliquing must only apply synthetic styling in cases where the font descriptors imply this is needed, rather than based on the style attributes implied by the font data.

Thanks for following-up. I don't think this is clear enough, because this sentence IMO still leaves room to interpret that synthetization may be required ("font descriptors imply...needed") if oblique or bold requested styles are outside the variable range. 

> However, variation values applied to fonts defined with '@font-face' will be clamped to both the values specified in these descriptors as well as the values supported by the font file itself.

This sounds to me more like it covers `font-variation-settings:`, and could do with a clarification that implied application of variation parameters (which happens for example for `font-weight`, translated to a `wght` variation axis value) are covered here as well.
