[Feature] 指定Tooltip的父节点

[viking7982]

What problem does this feature solve?

echarts的父组件设置了overflow:hidden，所以tooltips需要插入到父组件的外面。

虽然现在支持了body插入，但是我们业务的滚动元素不是body，所以插入到body也不能满足需求。

因此希望可以指定插入的DOM节点。

What does the proposed API look like?

tooltip.getAppendElement: e => e.closest('.scroll-container')

TITLE

[Feature] Specifies the parent node of the Tooltip

BODY

What problem does this feature solve?

The parent component of echarts has overflow:hidden set, so tooltips need to be inserted outside the parent component.

Although body insertion is now supported, the scrolling element of our business is not the body, so inserting it into the body cannot meet the requirements.

Therefore, it is hoped that the inserted DOM node can be specified.

What does the proposed API look like?

tooltip.getAppendElement: e => e.closest('.scroll-container')
