💡 What is the current behavior?

  • Enabling tab is not receiving proper visual focus indicator
  • disabled steps announced as 'clickable circle graphics'
  • add proper a11y semantic roles
  • space and enter key is not activating the step

JIRA : [IX-4340]

🆕 What is the new behavior?

  • focus indicator will have proper visibility
  • handled a11y semantics
  • space and enter key would be used to activate the workflow step

📝 Walkthrough

Walkthrough

Workflow steps now support Enter and Space activation on the interactive step element. They expose updated ARIA and tab semantics, use theme-based focus styling, and include accessibility and keyboard regression coverage. Storybook now includes a workflow example.

Changes

Workflow step accessibility

Layer / File(s) Summary
Interactive step behavior
packages/core/src/components/workflow-step/workflow-step.tsx, packages/core/src/components/workflow-step/workflow-step.scss
The interactive step element handles clicks and keyboard activation. It exposes dynamic accessibility attributes and uses theme-based focus styling. Decorative icons are hidden from assistive technology.
Accessibility and keyboard regression coverage
packages/core/src/components/workflow-steps/test/workflow-steps.ct.ts
Tests verify Axe compliance, ARIA attributes, tab behavior, hidden icons, and selection through Enter and Space.
Workflow story and release support
packages/storybook-docs/src/stories/workflow.stories.ts, packages/storybook-docs/.storybook/preview.ts, .changeset/friendly-workflow-keyboard.md
Storybook includes workflow step states, event logging, accessibility configuration, and default controls. Stories use alphabetical sorting. The changeset documents the update.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟡 Moderate · up to 30436

The workflow step now adds keyboard activation and accessibility semantics, but Space/Enter may be suppressed for focusable slotted content and the related test does not firmly protect the button-role behavior. This creates a bounded keyboard-accessibility regression risk that should be fixed or explicitly accepted before merge.

Code Review

This pull request introduces accessibility and keyboard navigation improvements to the workflow step components, including ARIA roles, dynamic labels, and support for Space and Enter key selection, backed by new component tests. The review feedback highlights a critical bug in getStepLabel where the aria-label is repeatedly appended with the status on subsequent renders, suggesting a caching mechanism. Additionally, the feedback notes a missing changeset for these user-facing accessibility changes and recommends exposing a customizable prop for the 'Step indicator' label instead of hardcoding it.

Important

The consumer version of Gemini Code Assist on GitHub is being sunset. Starting June 18, 2026, new organization installations will be blocked, and all code review activity will officially cease on July 17, 2026.

Return before suppressing activation keys on non-interactive steps.

tabIndex="-1" allows programmatic focus, but onKeyDown() suppresses Space and Enter for disabled or non-clickable steps without selecting them. Return from disabled or !clickable states before calling preventDefault().

Proposed fix
  onKeyDown(event: KeyboardEvent) {
+   if (this.disabled || !this.clickable) {
+     return;
+   }
    if (event.key === ' ' || event.key === 'Enter') {
      event.preventDefault();
      this.onStepClick();
    }

138-139: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Use an accessibility locator for the interactive element.

The test locates the internal .step class. It can still pass if role="button" is removed. Locate the step with getByRole('button') so the test validates the public accessibility contract.

Proposed fix
-    const first = page.locator('ix-workflow-step').nth(0).locator('.step');
-    const second = page.locator('ix-workflow-step').nth(1).locator('.step');
+    const first = page.locator('ix-workflow-step').nth(0).getByRole('button');
+    const second = page.locator('ix-workflow-step').nth(1).getByRole('button');

As per path instructions, component tests should use accessibility locators for user-facing contracts.
