How to set the spacing between the text of the flowchart node and the border?

[yuzhujiutian]

my markdown flowchart code is as follows:

```flow
story_approval( 需求立项 )
story_zgh-ing( 转规划ing )
story_zsx-ing( 转实现ing )

story_compound( 需求复盘 )
style story_compound fill:#F0F,stroke:#F00,stroke-width:1px;

classDef cssName fill:#FF0,stroke:#F00,stroke-width:1px;
class story_zsx-ing,story_zys-ing,story_zcs-ing cssName;

story_approval --> | 产品设计 | story_zgh-ing

story_approval .-> | 开发编码 | story_zsx-ing
story_zgh-ing --> | 开发评审OK | story_zsx-ing
story_zsx-ing --> story_compound
```

The output flowchart is as follows:

When I clicked the flowchart, I found that some text could not be displayed properly.

Hi! Sorry for the slow response.

The project has got good traction but it also means that it is very hard to manage all issues on your spare time. I am trying to get a bigger team together for faster development and better support #866.
I think this is a dupilcate of #790
