Markdown collapsible block doesn't render inline code

Markdown parser in GitLab projects and issue doesn't render inline code when used in a collapsible block.

Add a markdown file in a GitLab project with the following contents:

# markdown-test

<details>
<summary> `should be inline code` </summary>

contents

</details>

`should be inline code` is rendered.

should be inline code is rendered instead.

(If you can, link to the line of code that might be responsible for the problem)
