Linkify of GitHub Flavored Markdown not detecting inline formatting

[nerg4l]

Please answer the following before submitting your issue:

1. What version of goldmark are you using? : v1.4.0
2. What version of Go are you using? : 1.16.4
3. What operating system and processor architecture are you using? : Windows 10 Pro N 20H2 64 bit
4. What did you do? : Rendered links surrounded with inline formatting.
5. What did you expect to see? : Link formatted with strikethrough/bold/italic.
6. What did you see instead? : End of closing format are part of URL.
7. Did you confirm your output is different from CommonMark online demo or other official renderer correspond with an extension?: Yes

Creation:

var markdown = goldmark.New(goldmark.WithExtensions(extension.GFM))

It seems the default email regex parses differently.

Exact content:

__http://test.com/~/a__  
__http://test.com/~/__  
__http://test.com/~__  
__http://test.com/a/~__  

GitHub Flavored Markdown:

• http://test.com/~/a -> <strong><a href="http://test.com/~/a" rel="nofollow">http://test.com/~/a</a></strong><br>
• http://test.com/~/ -> <strong><a href="http://test.com/~/" rel="nofollow">http://test.com/~/</a></strong><br>
• http://test.com/~ -> <strong><a href="http://test.com/" rel="nofollow">http://test.com/</a>~</strong><br>
• http://test.com/a/~ -> <strong><a href="http://test.com/a/" rel="nofollow">http://test.com/a/</a>~</strong></p>

Goldmark render:

__<a href="http://test.com/~/a__">http://test.com/~/a__</a><br>
__<a href="http://test.com/~/__">http://test.com/~/__</a><br>
__<a href="http://test.com/~__">http://test.com/~__</a><br>
__<a href="http://test.com/a/~__">http://test.com/a/~__</a>
