URL: https://github.com/apache/echarts/issues/18266

### Link to Minimal Reproduction
_No response_
### Steps to Reproduce
1. Using the following link to create a heatmap chart:
https://echarts.apache.org/examples/en/editor.html?c=heatmap-large
2. Replacing line 11 in function generateData(theta, min, max) with the following 6 lines of code:
if (i> 10 && i<160) {
data.push([i, j, undefined]);
}
else {
data.push([i, j, noise.perlin2(i / 40, j / 20) + 0.5]);
}
3. click on Run button to generate the chart. Let your mouse cursor stay focused on the Run button. Do not move your mouse.
If you moved your mouse and remaining chart was drawn, click on Run button again, then immediately hands off your mouse to reproduce the problem.
### Current Behavior
No chart is drawn for x (i.e. i) > 160 and x <= 200.
### Expected Behavior
Chart shall be shown between x (i.e. i) > 160 and x <= 200.
### Environment
```markdown
- OS: Windows 10

[Heatmap_issue.pptx](https://github.com/apache/echarts/files/10725919/Heatmap_issue.pptx)
Above Heatmpa_issue.pptx contains a recorded video which shows how the issue can be reproduced.
Just click at Heatmpa_issue.pptx link to download and open it, then click at the play button at the bottom to see the video.
Explanation of the video:
In the beginning part of the video, after I copied & pasted the code and clicked the Run button. I intentionally moved my mouse to trigger the drawing of the remaining chart.
In the late part of the video, after I copied & pasted the code and clicked the Run button. I hand off my mouse to prevent trigger mouse event(點擊Run按鈕后，手馬上離開鼠標，以防移動鼠標trigger Event). You can see the rest part of chart was not drawn.
