从网页复制的下划线字符会带不可见的转义符

[d13-proto]

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. 复制网页中的下划线字符，例如这里的“__”
2. 粘贴到笔记里，显示为：__
3. 复制笔记里的 __
4. 粘贴到其他地方，显示为：\_\_

这是正常的，因为 _ 是 Markdown 标记符，如果要显示的话需要加转义 \_。
