Per shape() spec, the arc keyword interpolation rules are meant to match existing SVG <path> interpolation rules: flags are interpolated as fractions between zero and one, with any non-zero value considered to be a value of one. So path() should reasonably do the same for the arc flags at 0.125 and such. https://drafts.csswg.org/css-shapes-1/#interpolating-shape https://svgwg.org/specs/paths/#PathElement Differential Revision: https://phabricator.services.mozilla.com/D275122 bugzilla-url: https://bugzilla.mozilla.org/show_bug.cgi?id=2003903 gecko-commit: ae50a7cd7ce68e275af8e0dbcb86eaf5286b4227 gecko-reviewers: emilio, firefox-style-system-reviewers
