Markdown: reference-style links broken across newline

[harding]

What version of Hugo are you using (hugo version)?

$ hugo version
hugo v0.87.0-B0C541E4+extended linux/amd64 BuildDate=2021-08-03T10:57:28Z VendorInfo=gohugoio

Does this issue reproduce with the latest release?

Yes (this is the latest release).

Issue

Reference-style links broken across a newline are incorrectly rendered. For example, this text:

This is a [test][foo
bar] 1...2..3...

[foo bar]: /

Produces this output:

CommonMark says it should render correctly: https://spec.commonmark.org/dingus/?text=This%20is%20a%20%5Btest%5D%5Bfoo%0Abar%5D%201...2..3...%0A%0A%5Bfoo%20bar%5D%3A%20%2F

Relevant config file:

[markup]
  [markup.goldmark]
    [markup.goldmark.extensions]
      definitionList = true
      footnote = true
      linkify = true
      strikethrough = true
      table = true
      taskList = true
      typographer = true
    [markup.goldmark.parser]
      autoHeadingID = true
      autoHeadingIDType = "github"
      [markup.goldmark.parser.attribute]
        block = false
        title = true
    [markup.goldmark.renderer]
      hardWraps = false
      unsafe = true
      xhtml = false

(Thanks for all your work!)
