The Spinner default "Contents" aria-label was emitted by an inline conditional in the JSX, so the props table for the component did not show that there was a default value at all (patternfly#11750). Move the default to the destructuring pattern so react-docgen surfaces it, and replace the three conditional spread expressions with a direct attribute plus the still-conditional aria-labelledBy spread. Existing snapshots are unchanged (`<Spinner />` still renders with aria-label="Contents"). Added unit tests cover the default value, an explicitly provided aria-label, and aria-labelledBy. Closes patternfly#11750

26-26:⚠️ Potential issue | 🟡 Minor | ⚡ Quick winPre-existing:
aria-labelledByis not a valid ARIA attribute name.The WAI-ARIA spec defines this attribute as
aria-labelledby(all lowercase). React passesaria-*attributes as-is to the DOM without normalization. On an SVG element (XML-based, case-sensitive),'aria-labelledBy'produces a non-standard DOM attribute that assistive technologies will not recognize.Lines 26, 36, and 46 in Spinner.tsx are pre-existing. However, the new test at lines 19–21 in Spinner.test.tsx adds coverage for this prop with the incorrect spelling, perpetuating the issue in new code. A full fix would require renaming the public prop from
'aria-labelledBy'to'aria-labelledby'(a breaking API change best addressed in a dedicated PR), but now is a good time to track this known issue.🤖 Prompt for AI Agents

New test codifies the pre-existing aria-labelledBy (wrong casing) behavior.
The prop and assertion both use aria-labelledBy (capital B). Since React camelCases all attributes except data-* and aria-*, it passes aria-* names as-is to the DOM. On the SVG element (XML/case-sensitive), this produces a non-standard aria-labelledBy attribute that screen readers won't find — they look for aria-labelledby (all lowercase, per WAI-ARIA spec).
The test will pass today (JSDOM stores aria-labelledBy exactly as written and toHaveAttribute finds it), but it is asserting broken accessibility behavior. The correct attribute name throughout — interface, component, and test — should be aria-labelledby.
✅ Corrected test (aligned with WAI-ARIA spec)
test('renders aria-labelledBy when provided', () => {
- render(<Spinner aria-labelledBy="external-label" />);
- expect(screen.getByRole('progressbar')).toHaveAttribute('aria-labelledBy', 'external-label');
+ render(<Spinner aria-labelledby="external-label" />);
+ expect(screen.getByRole('progressbar')).toHaveAttribute('aria-labelledby', 'external-label');
});The full fix also requires renaming the prop in SpinnerProps from 'aria-labelledBy'?: string to 'aria-labelledby'?: string and updating the corresponding destructuring and spread in Spinner.tsx. Because that is a public API rename, it may warrant its own PR and a deprecation notice.

What: Closes #11750
The Spinner component's default
aria-labelof "Contents" was emitted by an inline conditional in the JSX ({...(!ariaLabel && !ariaLabelledBy && { 'aria-label': 'Contents' })}), so the props table for the component didn't show that there was a default value at all. Per the maintainer's edit on the issue, this PR is scoped to just updating how that default is defined.The destructuring now sets the default directly:
and the three conditional spreads in the JSX collapse to a direct
aria-label={ariaLabel}plus the still-conditionalaria-labelledByspread.Behavior
<Spinner />still rendersaria-label="Contents".aria-labelcontinues to take precedence.aria-labelledBywill now also see the defaultaria-label="Contents"on the SVG. The two ARIA attributes coexist (per WAI-ARIA, an assistive technology will usearia-labelledbywhen both are present), and this matches the existing pattern for sibling components likeTabAction,DrawerCloseButton,PageToggleButton, andFileUploadFieldthat all use destructuring defaults foraria-label.Tests
Added three unit tests covering the default value, an explicitly provided value, and
aria-labelledBypropagation. Existing snapshot tests still pass unchanged.Summary by CodeRabbit
