Improve cursor position after deletion

[heheda123123]

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

1 先随便写点内容，然后创建一个代码块，里面随便写点内容

2 光标从代码块最后开始删除，比如图中，按三次删除，会发现光标直接到了上一段的开头，应该是在末尾才对吧

Expected result

删光代码块内容后，光标到上一段的末尾
