Summary
renderGettingStartedTipIfNeeded_gettingStartedTipPartguard assignment before the DOM append so re-entrant calls see the guard and return earlydom.clearNode(tipContainer)before append as a defensive measure against stale nodesRoot Cause
When
ChatTipContentPartis constructed, context-key changes can synchronously trigger another call torenderGettingStartedTipIfNeeded. The guard (this._gettingStartedTipPart.value) was set aftertipContainer.appendChild(), so the re-entrant call would pass the guard check, create a second tip, and append it -producing the "multiple identical tips stacked" symptom.Fix
Reorder the method so that:
this._gettingStartedTipPart.value = store) is set before any DOM mutationdom.clearNode(tipContainer)clears any stale nodes before appending the new tip
