百度地图与scatter结合，拖动地图后，tooltip位置显示移位

[AggerChen]

One-line summary [问题简述]

使用百度地图显示scatter点，配置tooltip显示每个点的信息。不管tooltip是跟随鼠标还是固定位置，当地图缩放并拖动后，tooltip显示位置偏移，甚至偏移到显示区域之外。confine:true控制显示在图形之内也不管用

Version & Environment [版本及环境]

• ECharts version [ECharts 版本]:3.8.4
• Browser version [浏览器类型和版本]:chrome 62.0.3202.62
• OS Version [操作系统类型和版本]:win7

Expected behaviour [期望结果]

tooltip能根据配置显示，不会因为地图拖动而偏移

ECharts option [ECharts配置项]

option = {
progressive:10000,

	                zoom: 10,
