Limited Availability Fonts

Font metric overrides

The ascent-override, descent-override, and line-gap-override descriptors adjust the display of a font declared in an @font-face statement. This can help make fallback fonts look the same size.

Baseline Status: This feature is currently Limited (not yet Baseline). Latest engine implementation shipped on Jun 1, 2021.
