Undo exception after deleting some blocks

[Wetoria]

非编辑块删除后撤销异常

Is there an existing issue for this?

• I have searched the existing issues

Can the issue be reproduced with the default theme (daylight/midnight)?

• I was able to reproduce the issue with the default theme

Could the issue be due to extensions?

• I've ruled out the possibility that the extension is causing the problem.

Describe the problem

删除html可以重复撤回，并且得到的结果为实际的html内容，具体见视频。

Expected result

不应该可以进行第二次撤回
