[I] [Bug] Label disappear in emphasis state when Pie sets "minShowLabelAngle" property [echarts]
kayla3love opened a new issue, #19625:
URL: https://github.com/apache/echarts/issues/19625
### Version
5.5.0
### Link to Minimal Reproduction
https://codesandbox.io/s/vfdn23
### Steps to Reproduce
1、Wait for all setTimeout functions to complete execution.
2、Move the mouse over the blue sector to enter the highlight state.
3、Both the label and labelLine of the blue sector disappear.
4、Move the mouse out of the blue sector, and the label and labelLine return to normal.
### Current Behavior
Now dynamically update the dataset of the pie chart, changing Series A's value from Value1 to Value2, and then back to Value1.
1、If the minShowLabelAngle property is not set, everything runs normally.
2、If set minShowLabelAngle property, and the sector angle corresponding to Value1 > `minShowLabelAngle` while the sector angle corresponding to Value2 < `minShowLabelAngle`, then after the value of Series A is restored to Value1, the label and labelLine of the corresponding sector in highlight state will disappear
### **Possible Reason**：
When value changes to Value2，`label.ignore` and `label.emphasis.ignore` is true
When value back to Value1，`ignore` is false but `emphasis.ignore` is true
### Expected Behavior
When value back to Value1，label and labelLine appear in in highlight state
### Environment
```markdown
- OS: macOS Ventura 13.4
- Browser: Chrome 121.0.6167.184
```

@helgasoft Possible problems:
```
if(stateShow !== showNormal){
stateObj.ignore = !stateShow
}

API for [minShowLabelAngle](https://echarts.apache.org/en/option.html#series-pie.minShowLabelAngle) says _"If a sector is less than this angle (0 ~ 360), label and labelLine **will not** be displayed."_
Your _minShowLabelAngle_ is 10 and therefore the value of 0 does not show up.
📌 please close issue if problem solved.

In Demo，Value then changes from 0 to 180，180deg is larger than minShowLargeAngle，but label disappears in emphasis state，appears in normal state

ok, I see it now, you are right - emphasis label is missing even though it should show up in accordance with the new data.
