packages/react/src/CounterLabel/CounterLabel.types.test.tsx:10

• Tests for ref forwarding and custom span prop acceptance were removed. Consider reintroducing showAcceptARef and shouldPassThroughSpanProps to maintain verification of these typings.

export function showAcceptARef() {

packages/react/src/AnchoredOverlay/AnchoredOverlay.test.tsx:3

• Axe accessibility tests were removed in this migration. Reintroduce accessibility checks or an equivalent approach to preserve a11y coverage for AnchoredOverlay.

import {AnchoredOverlay} from '../AnchoredOverlay'

packages/react/src/ActionBar/ActionBar.test.tsx:2

• Accessibility (axe) test cases were removed. Ensure you add back accessibility validations to catch regressions in the ActionBar component.

import {describe, expect, it, afterEach, vi} from 'vitest'
