1，页面的DOM节点过度，每次重排浏览器需要计算时间较多时。

Research direction
Start by reviewing the reproduction details and the referenced issue 169, then reproduce the tooltip behavior on a page with many DOM nodes and a slower device. Trace the tooltip positioning or measurement path responsible for the forced reflows; done means reducing unnecessary reflows without breaking tooltip placement.
