* Hide chart tooltips on exit; browser behavior checked on 2026-09-27.
* ECharts 6 manual hideTip also calls hideLater(hideDelay), so use hideDelay: 0.
* The old 999999 value delayed every hide path. ECharts handles ordinary exits;
* this wrapper handles missed events:
* - globalout when the pointer leaves the canvas;
* - document mousemove outside this chart, including its tooltip children,
* when selecting a point expands a summary and moves the canvas without mouseout,
* or WebView2 misses mouseout;
* - document mouseout with no relatedTarget when leaving the application window;
* - window blur when changing apps or clicking the title bar.
* Returns cleanup for component unmount.

* indicating blank canvas. Do not apply to axis-triggered charts, whose
* grid areas intentionally retain tooltips.
