Original GitHub issue: https://github.com/DavidAnson/markdownlint/issues/544

Rule MD053 incorrectly complains about an unused link definition when the link usage:

Spans 2 lines
Is in a blockquote

Reproducing

The following MarkDown file should reproduce the error:

<!-- error.md -->

# Example Blockquotes

Example 1: newline in link, working

> Find out more in the GitHub Actions documentation on [`push` events], [branch
> and tag filters], and [path filters].

Example 2: newline in link, not working

> Find out more in the GitHub Actions documentation on [`repository_dispatch`
> events] and [`workflow_dispatch` events].

@DavidAnson commented on GitHub (Aug 1, 2022):

The problem is when the shortcut link spans multiple lines in a block quote. Your example 2 doesn't seem to demonstrate that because it uses the same link from example 1. Removing example 1 generates a failure.
