[Anabelle]

Bug Report:

Description

HTML comments containing reference link definitions crash the preview window

Steps to Reproduce

1. Add the following comment to anywhere in an ADR.
   <!--[^1]:https://example.com -->
2. Open the ADR with log4brains preview / Reload the ADR if it's already open

Expected Behavior

Renderer does not crash, and also does not display commented text

Context

I was commenting out a reference link definition with my IDE. This issue came up when trying to do research to make a feature request to fully support reference links, including non-/\^[0-9]+/ shortcut reference links and implict reference links.

Environment

• Log4brains version: 1.0.1
• Node.js version: 18.16.1
• OS and its version: Fedora 38
• Browser information: Firefox 116.0
