Originally found when testing my repo: https://github.com/CarterLi/echarts-with-offscreencanvas
I tested several chart types and found only line chart worked as expected. I have been trying to debug this issue for 2 days and only found the issue happens here:
```js
_startLoop: function () {
var self = this;
this._running = true;
function step() {
if (self._running) {
requestAnimationFrame(step);
!self._paused && self._update();
}
}
requestAnimationFrame(step);
},
```
Of course it was not true, so I gave up.
The issue is rather important to our company, please help

@CarterLi
```js
option = {
// Set this to avoid the issue.
hoverLayerThreshold: Infinity,
...
};
```

And it needs to be fixed that:
1. Disable the feature of hover layer in when the root dom is canvas
2. Make worker case into the `test/**`.
