1. What version of goldmark are you using? : Latest from master i.e. v1.1.21 or faaafa55b6dfe9b833032a9728ef82e8f34d0b15
2. What version of Go are you using? : go version go1.13.5 linux/amd64
3. What operating system and processor architecture are you using? : Fedora 31 on amd64
4. What did you do? :

   
   package main

import ( "fmt" "github.com/yuin/goldmark" "bytes" )

func main() { source2 := [This link won't be rendered correctly](https://geeksocket.in/some-long-link-here "This is the place where everything breaks")

var buf bytes.Buffer
if err := goldmark.Convert([]byte(source2), &buf); err != nil {
    panic(err)
}
fmt.Println(buf.String())

}

5. What did you expect to see? :
The link should get rendered correctly with title attribute set.
6. What did you see instead? :
It get's rendered as
```html
<p>[This link won't be rendered
correctly](https://geeksocket.in/some-long-link-here &quot;This is the
place where everything breaks&quot;)</p>

7. Did you confirm your output is different from CommonMark online demo or other official renderer correspond with an extension?: Yes.

I tried going trough the source code and debug this issue, but I wasn't able to completely understand what all is happening in parseBlock function here https://github.com/yuin/goldmark/blob/master/parser/parser.go#L1106 For the link label it advances the next line segment correctly but for the title text it doesn't. Would like to send a fix if anyone can help me to understand why it's failing.
