Problem

Hover a playground link under "Try it out", click it, and it opens in a new tab. Come back to the npmx tab and the tooltip is showing again, with the pointer nowhere near the link, and it keeps floating over the page while you scroll.

The click leaves the link focused. When the tab regains focus the browser fires focusin again, and TooltipApp shows the tooltip on any focus, so it comes back on its own. Nothing hides it afterwards unless you hover the link and leave it again.

Fix

  • Only show the tooltip on focus when the trigger matches :focus-visible. Keyboard users still get the tooltip when they tab to the element, a pointer click no longer counts.
  • Hide an open tooltip when the tab becomes hidden or the window loses focus, so it does not sit there while you are away. Those listeners are only attached while a tooltip is open.

Before / after

threejs.mp4

Tests

Added tests in test/nuxt/components/Tooltip.spec.ts for the focus behaviour and for hiding on window blur and on visibility change.

Also added a Playwright test in test/e2e/tooltip.spec.ts that runs the real browser path: hover a tooltip trigger, click it, move the pointer away, then refocus the trigger the way returning to the tab does. It fails against the code before this fix and passes after it.

pnpm lint:fix, pnpm test:types and pnpm test all pass locally.

A pointer click leaves the trigger focused, so the browser fires focusin
again when the tab regains focus and the tooltip reopens with no pointer on
it. Only show the tooltip for focus-visible triggers, and hide an open
tooltip when the tab is hidden or the window loses focus.

📝 Summary

Summary by CodeRabbit

  • Bug Fixes

    • Tooltips now appear only when the trigger receives keyboard-visible focus, avoiding display after pointer interaction.
    • Tooltips now close when the window loses focus or the page becomes hidden, preventing stale tooltips when returning to the page.
    • Tooltips remain hidden when focus returns to a trigger following pointer interaction.
  • Tests

    • Added coverage for keyboard versus pointer focus, tooltip dismissal during window blur and document visibility changes, and focus restoration after clicking a trigger.

Walkthrough

The Tooltip component now opens only for keyboard focus. It hides immediately when the window or page loses focus or visibility. Tests cover keyboard focus, pointer focus, blur, and visibility changes.

Changes

Tooltip behaviour

Layer / File(s) Summary
Keyboard focus activation
app/components/Tooltip/App.vue, test/nuxt/components/Tooltip.spec.ts, test/e2e/tooltip.spec.ts
The tooltip uses :focus-visible to accept keyboard focus and ignore pointer-driven focus. Unit and end-to-end tests cover both focus paths.
Page focus and visibility dismissal
app/components/Tooltip/App.vue, test/nuxt/components/Tooltip.spec.ts
The tooltip clears pending hide timers and hides on blur, pagehide, or hidden visibilitychange events. Tests cover hidden and retained page visibility.

Priority: ⬇️ Low — Defer the tooltip behavior fix because it is a narrow UI usability change with focused unit and end-to-end coverage.

Merge Risk: ⚪ Minimal · up to 74714

Tooltip focus and page-dismissal behavior is updated with accompanying test coverage, with no remaining merge-blocking risk identified.

instance rather than Document.prototype, so cleanup restores the initial
own-property state and does not alter the global object shape for later tests.

Comment thread test/nuxt/components/Tooltip.spec.ts Outdated
Covers the real Chrome behaviour the fix relies on: a pointer click focuses
the trigger without making it :focus-visible, so refocusing it must not
reopen the tooltip. Fails against the code before the fix.
The descriptor was read from Document.prototype, so cleanup re-defined the
getter as an own property on document instead of removing the stub. Read the
own descriptor so the delete path runs and document keeps its original shape.
