Hello @soundlake ,
I am new to this community and would like to take on this task. Could you please assign it to me?

@VANSH3104 I'm not in the team, either, and I don't have right to assign a bug to anyone. As this is an open source project, you could fork the repo, and make a fix and pull request.

Thanks for your report! Yes, this is a known issue of SVG. There is a old in-progress PR ecomfe/zrender#792.
