Greptile Summary

Fixed tooltip closing immediately on mouse leave by implementing controlled state with delayed closing (300ms) and mouse event handlers on both trigger and content. Added singleton pattern to ensure only one GitHub issue tooltip is open at a time.

• Converted from uncontrolled to controlled Radix Tooltip with manual state management
• Added 300ms delayed closing via scheduleClose() that can be canceled when mouse re-enters
• Implemented module-level singleton (activeTooltipForceClose) to force-close other tooltip instances
• Added onMouseEnter/onMouseLeave handlers to both TooltipTrigger and TooltipContent for hover persistence

Confidence Score: 3/5

• Safe to merge with one logical issue that could cause memory warnings
• Implementation correctly fixes the tooltip closing issue, but missing timer cleanup on unmount could cause React warnings about state updates on unmounted components. The singleton pattern works correctly, and the delayed closing logic is sound.
• src/renderer/components/GitHubIssuePreviewTooltip.tsx needs timer cleanup in useEffect

stableForceClose.current is assigned once but never updated - should be initialized directly without wrapping in a ref

Suggested change

	const stableForceClose = useRef<() => void>(() => latestClose.current());
	const stableForceClose = useRef<() => void>(() => {
	cancelClose();
	setOpen(false);
	});

Timer cleanup needed - if component unmounts while closeTimer is active, it will still fire and try to update state
