Initial checklist

• I agree to follow the code of conduct
• I searched issues and discussions and couldn’t find anything (or linked relevant results below)

Affected packages and versions

Link to runnable example

No response

Steps to reproduce

当我输入[的时候，[的前面会出现一个多余的\。

导致无法使用 Link和 Img，因为Link和Img是[开头。在官方的Playgroud中也出现了这个现象

eg:
当我输入

[百度](http://www.baidu.com/)

在md源码中会被解析成

\[百度]\(http\://www\.baidu.com/)

最终导致Link无法显示

Meeting the same problem, cannot type any links.

Same here.

@Saul-Mirone do you have a plan/idea how to fix this?

Same issue (but trailing slash) with using Shift+Enter and then typing anything.

Edit: Found syntax-tree/mdast-util-to-markdown#45
It looks intentional for this trailing slash. Although, this is not standard markdown syntax.

I'm seeing this as well. If I include a [ in the initial value, it is parsed correctly and links work. But if a [ is typed into the editor, it is escaped with . This means links are impossible to create in the editor, including in the Playground.

I've tested that this issue was introduced in 7.3.3 and still exists in 7.3.6. Reverting to 7.3.2 resolves the problem.
