Thanks! I’ve now completed the questionnaires and requested or
self-certified the Privacy, Security, Enterprise, Debuggability,
Testing, and Adoption gates as appropriate in ChromeStatus.
I’ve also updated the expected shipping milestone to 154, since M153
has already branched.
Please let me know if anything else is needed.

>> Exposes the width attribute on FontFace and the @font-face
font-width descriptor as aliases for stretch and font-stretch.
Aligns Chromium with the updated CSS Font Loading and CSS Fonts 4
specifications. Developers can now inspect or initialize font face
widths using FontFace.width and CSS font-width interchangeably
with stretch and font-stretch.

>> Motivation
>> CSS Font Loading and CSS Fonts 4 define width as the primary
FontFace descriptor attribute and @font-face descriptor, while
retaining stretch as a legacy alias. Chromium previously ignored
the width constructor member and font-width descriptor, causing
Web Platform Tests to fail. Exposing width aligns Chromium with
the updated specification.
