[Bug] Gaps between stacked bar chart data series

### Version

5.4.2

### Link to Minimal Reproduction

[https://codepen.io/rjmqvuul-the-bashful/pen/MWMjGrV](https://github.com/apache/echarts/issues/url)

### Steps to Reproduce

Normal stacked bar

### Current Behavior

gaps appear (apparently from the first value of the series) between stack bars which cause the total of the bar to not line up with the y axis


previous post reporting the same issue:

https://github.com/apache/echarts/issues/15936

### Expected Behavior

I would expect the bars to stack the data series on top of each other without gaps and the total of the series line up to the yaxis value

### Environment

```markdown
- OS: Windows 11
- Browser: Chrome most recent version
- Framework: Angular
```
