Conversation
Propagation test now also asserts locate is emitted in the same interaction, so it would catch a broken handler that stops propagation without emitting. Keyboard test uses explicit .focus() instead of user.tab() to avoid relying on JSDOM implicit tab order. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

…15612) *PR Created by the Glary-Bot Agent* --- Fixes the failing `test` job on #15413. Targets that PR's branch, so merging this here makes #15413 green. ## Problem `emitted()` returned by `@testing-library/vue`'s `render()` reports events for the component handed to `render()` — internally it is just `emitted: name => wrapper.emitted(name)` on the mounted root. The propagation test renders an ad-hoc wrapper, so the root is the `<div>`, not `LocateNodeButton`. The wrapper never emits `locate`; only the child does. So `emitted().locate` was `undefined` and `expect(undefined).toHaveLength(1)` threw: ``` AssertionError: Target cannot be null or undefined. ❯ LocateNodeButton.test.ts:44:30 ``` Dumping what the wrapper actually reports confirms it — only native events that bubbled to the root element, and notably no `click`, which independently shows `@click.stop` is working: ``` pointerover, pointerenter, mouseover, mouseenter, pointermove, mousemove, pointerdown, mousedown, focusin, pointerup, mouseup ``` The assertion could never pass, regardless of component behavior. The component itself is fine — no regression. ## Fix Spy on the child's `@locate` handler instead of reading the wrapper's `emitted()`. `@vue/test-utils` `findComponent()` is not an option here — `docs/guidance/vitest.md` bans it in new tests — and `render()` exposes no way to reach a child's emitted events. ## Verification - `pnpm vitest run src/components/rightSidePanel/errors/LocateNodeButton.test.ts` — 4/4 pass - `pnpm vitest run src/components/rightSidePanel` — 208/208 pass - `pnpm typecheck` (exit 0), `pnpm format:check`, ESLint on the changed file — all clean The assertion keeps its teeth. Replacing `@click.stop="emit('locate')"` with `@click.stop="() => {}"` — precisely the swallowed-emit case the original PR set out to catch — still fails: ``` AssertionError: expected "vi.fn()" to be called 1 times, but got 0 times ❯ LocateNodeButton.test.ts:45:22 ``` Co-authored-by: Glary-Bot <glary-bot@users.noreply.github.com>

Summary
Two small follow-ups from the #13401 review:
emitted().locatehas length 1 in the same interaction. Without this, a broken handler that callsevent.stopPropagation()but silently swallows the emit would still pass.user.tab()(implicit JSDOM tab order) with explicit.focus()on the button, making the test self-contained and immune to tab-order assumptions in the test environment.The old implicit-tab-order keyboard test is removed; the new explicit-focus version covers the same behavior more robustly.
