**TITLE**
[Bug] In touch screen devices, echarts.getZr().on('mouseover') does not
return any blank space, but the document says that the mouse can trigger
zrender's mouse event anywhere.
**BODY**
### Version
5.4.3
### Link to Minimal Reproduction
https://echarts.apache.org/examples/zh/editor.html?c=map-HK
### Steps to Reproduce
I detected the mouseover event in a touchscreen device, and the mouseover
triggered normally in the case of a target, and the mouseover did not fire
properly in the area where there was no target (i.e. in the empty space). When
I switched to a monitor without touchscreen capabilities, the mouseover
triggered in both targeted and untargeted areas.
I think this is due to a touchscreen compatible bug in zrender.
```
myChart.getZr().on('mousemove', function(event){
console.log('onmousemove!!!!')
})
```
### Current Behavior
In touchscreen devices, Zrender's mouseover does not trigger mouse events
for untargeted areas (i.e. empty spaces), the click event is normal, and white
spaces can also be fired, but the mouseover is abnormal
### Expected Behavior
On touchscreen devices, the zrender mouseover should also fire in the same
empty space as the click event, as the documentation says "zrender events are
different from echarts events." The former is triggered when the mouse is
triggered anywhere, while the latter is triggered only when the mouse is on a
graphic element. “
