Add a skeleton implementation of FontFaceSet interface with support for resolving the `document.fonts.ready` Promise when the loading of web fonts is completed. This change exposes new failures in the web platform tests. These were ERROR before the change because `document.fonts.ready` caused a `ReferenceError` causing the tests to be aborted and they now FAIL: - /css/CSS2/linebox/vertical-align-top-bottom-001.html - /css/css-flexbox/flex-one-sets-flex-basis-to-zero-px.html - /css/css-fonts/generic-family-keywords-001.html - /css/css-fonts/math-script-level-and-math-style/math-script-level-004.tentative.html - /css/css-fonts/math-script-level-and-math-style/math-script-level-002.tentative.html - /css/css-text/text-autospace/text-autospace-ligature-001.html - /css/css-values/calc-size/calc-size-width.tentative.html These were TIMEOUT before the change because `document.fonts.ready` was a ReferenceError and the tests were asynchronous (reftest-wait). These now FAIL because the assertions are now executed after fonts are loaded: - /css/css-fonts/matching/fixed-stretch-style-over-weight.html - /css/css-fonts/matching/range-descriptor-reversed.html - /css/css-fonts/matching/stretch-distance-over-weight-distance.html - /css/css-fonts/matching/style-ranges-over-weight-direction.html - /css/css-fonts/variations/variable-box-font.html - /css/css-fonts/variations/variable-gpos-m2b.html - /css/css-fonts/variations/variable-gsub.html - /css/css-fonts/variations/variable-opsz-size-adjust.html - /css/css-position/sticky/position-sticky-change-top.html - /css/css-position/sticky/position-sticky-fixed-ancestor.html - /css/css-position/sticky/position-sticky-flexbox.html - /css/css-position/sticky/position-sticky-grid.html - /css/css-position/sticky/position-sticky-inline.html - /css/css-position/sticky/position-sticky-rendering.html - /css/css-position/sticky/position-sticky-stacking-context.html - /css/css-position/sticky/position-sticky-table-td-left.html - /css/css-position/sticky/position-sticky-table-td-right.html - /css/css-position/sticky/position-sticky-table-tfoot-bottom.html - /css/css-position/sticky/position-sticky-table-th-right.html - /css/css-position/sticky/position-sticky-table-thead-top.html - /css/css-position/sticky/position-sticky-table-tr-bottom.html - /css/css-position/sticky/position-sticky-table-tr-top.html - /css/css-position/sticky/position-sticky-writing-modes.html - /css/css-pseudo/marker-intrinsic-contribution-001.html - /css/css-text/hyphens/hyphens-character.html These tests now PASS due to this patch: * FAIL -> PASS - /html/canvas/element/text/2d.text.draw.fill.maxWidth.fontface.html - /html/canvas/element/text/2d.text.measure.width.empty.html * TIMEOUT -> PASS - /css/css-fonts/variations/font-descriptor-range-reversed.html - /css/css-fonts/variations/variable-opsz.html - /css/css-position/sticky/position-sticky-table-th-left.html * ERROR -> PASS - /css/css-fonts/generic-family-keywords-002.html - /css/css-fonts/generic-family-keywords-003.html * These two tests only PASS in Layout 2020: - /css/CSS2/positioning/inline-static-position-001.html - /css/cssom-view/getBoundingClientRect-empty-inline.html These two tests have subtests that PASS intermittenttly: - /fetch/metadata/generated/css-font-face.sub.tentative.html - /css/css-fonts/generic-family-keywords-001.html These tests are new TIMEOUTS that used to FAIL because `documents.fonts.ready` was undefined: - /resource-timing/TAO-match.html - /resource-timing/content-type.html - /resource-timing/nextHopProtocol-is-tao-protected.https.html The failure in `/resize-observer/change-layout-in-error.html` could be due to an issue in the ResizeObserver implementation that is now exposed with this change, but this needs more investigation.
