Rendering of Markdown links inside HTML tags doesn't work as expected

Markdown links e.g. in comments are sometimes not rendered properly when inside HTML elements such as <details>. Adding a blank line around the link seems to solve the problem.

Example 1

Input:

<details>
[foo]
</details>

[foo]: https://foo.org

Expected output:

foo

Actual output:

[foo]

Example 2

Input:

<details>

[foo]
</details>

[foo]: https://foo.org

Expected output:

foo

Actual output:

foo
