Steps to Reproduce

markPoint：{
label: {
show: true,
padding,
borderRadius: 4,
backgroundColor: '#fff',
shadowBlur: 5,
overflow: 'breakAll',
shadowColor: 'rgba(0, 0, 0, 0.1)',
shadowOffsetX: 2,
formatter: param => {
const { labelData } = param.data;
const labelContent = labelData.reduce((prev, cur) => {
return ${prev}\n${cur};
});
return {text|${labelContent}};
},
rich: {
text: {
color: isDark ? '#eeeeee' : '#333',
fontSize: 14,
lineHeight,
width: 10,
},
},
},
}

Current Behavior

--采用之前的markpoint配置，当label中的富文本配置了宽度，且Label的文本里应用了该富文本，当Label的文本足够长需要换行的时候可以复现该问题

Expected Behavior

期望设置了富文本宽度当文本过长后能正常换行无任何报错

Environment

- OS:window
- Browser: Chrome
- Framework:React

TITLE

[Bug] markPoint.label.rich Setting the width of rich text causes an empty pointer exception

[helgasoft]

A null pointer exception occurs after setting the width of the rich text using markPoint.label.rich

Cannot reproduce the null pointer exception in v.6.1.0.
rich.text.width is just for styling (text box size width). It is not related to overflow, but will replace label.width and disable overflow if set.
