Fixes #11644
Firefox 148+ silently drops focus from a slotted element when the
<slot>it was projected through is reassigned during the shadow-DOM re-render in__renderItemWrappers. Noblurorfocusoutevents fire —document.activeElementsimply becomes<body>after the next frame.Cache the focused element before the re-render and re-focus it inside the existing
requestAnimationFrameblock when it lost focus and its wrapper was not removed.The existing focus tests in `packages/dashboard/test/dashboard.test.ts` cover the regression scenarios. They pass on Firefox 144 (current CI) regardless of the fix and will start exercising it once CI moves to Firefox 148+ via the upcoming Playwright bump.
