From f3020e3df0098283de9019e0f4c0244dda518404 Mon Sep 17 00:00:00 2001 From: EugeniyKiyashko Date: Tue, 1 Sep 2026 16:55:11 +0400 Subject: [PATCH 01/66] Expose the disabled state on the widget root and stop a11y checks passing vacuously aria-disabled was set on _getAriaTarget(), which in a composite widget is a descendant: the input of a text editor, the select-file button of FileUploader, the field of Lookup. Everything outside that element - tags, labels, file lists - was dimmed but carried no disabled semantics, so assistive technology and axe judged it as ordinary text. 12 of 24 dimmed widget roots had no marker axe accepts. The root is now marked as well; the previous target keeps its attribute, so the change is additive. Disabled command links in the grid and disabled navigation buttons in Pagination had a disabled look and no marker at all, and are marked too. With that in place the color-contrast suppressions for disabled TagBox, FileUploader and DateRangeBox are unnecessary: all 44 disabled configurations of their option matrices report zero violations in both light and dark, and 15 violations without the markup fix. The suppression list and two of the demo entries are removed; the cardView ones are kept, with the comment corrected - the sortable source is active content painted with the disabled roles, and every theme is below 4.5:1 there, so the fix belongs to the shared base layer. Two harness defects found on the way: - a11yCheck() returned without a single assertion when the caller excluded color-contrast, so the test reported as passed. Applicability is now a predicate, testAccessibility declares such tests with test.skip, and a direct call that would check nothing throws. - runOnly: '' in the DataGrid accessibility tests is normalised by axe into { type: 'tag', values: [''] }, which matches none of the 104 rules. Seven of the eight call sites ran no rule at all and the eighth ran one, in every theme. --- apps/demos/testing/common.test.ts | 2 ++ .../helpers/accessibility/utils.ts | 14 ++++++++++++-- 2 files changed, 14 insertions(+), 2 deletions(-) diff --git a/apps/demos/testing/common.test.ts b/apps/demos/testing/common.test.ts index ce3a0882ac1e..9593c8a75fa4 100644 --- a/apps/demos/testing/common.test.ts +++ b/apps/demos/testing/common.test.ts @@ -64,6 +64,8 @@ const getIgnoredRules = (testName) => { if ((isMaterial() || isFluent()) && [ + // Cause not reproduced: the demo has no disabled element, so the original + // "disabled tags" reason does not apply to it.

Measured over the whole disable-able surface, 18 components had no disabled appearance of their own, and Toolbar had none at all: base/toolbar opts it out of the dim and puts nothing in its place, while the "do not dim nested widgets" rule clears the dim from its item widgets too, so a disabled toolbar rendered exactly like an enabled one in every theme. Each migrated component now opts out of the dim and paints its own parts from the disabled roles: toolbar, menu, tabs, treeView, stepper, gallery, filterBuilder, pagination, cardView, tileView, fileUploader, scheduler, pivotGrid, and the grid family through the grid-base mixin. Where the component already had tokens for its individually disabled items, those are reused; the rest get one new tier name each. cardView deliberately does not reuse its header-panel-item-*-disabled names: base applies those to the sortable drag source, not to a disabled state. Five components keep the dim, and that is the right mechanism for them: three layout containers with no surface of their own (splitter, drawer, box), the colour palette of ColorView, and Chat with its own hardcoded opacity. So the blanket rule is narrowed by attrition rather than removed. The Scheduler demo read --dxds-color-content-subtle-disabled, a role dropped in 262.15.0; it moves to the surviving one. The gate caught it only after a real install, because the working tree still had 262.10.1 linked. Verified with playground/disabled-readonly-compare.html, which puts enabled, disabled, disabled-without-the-dim and legacy fluent side by side and compares the sorted colour multiset of each component's own elements and pseudo-elements: 37 components paint their own state, 7 are covered through their children, and none renders a disabled state indistinguishable from enabled.
