Describe the bug

The LSP parses commented out links as "real" links, and does not report them as missing backlinks. zk edit --missing-backlink properly ignores commented-out links.

How to reproduce?

Example:

<!-- Cooperating is key to avoid [reinventing the wheel](ms2u). -->

zk configuration

[lsp.diagnostics]
dead-link = "error"
missing-backlink = { level = "warning", position = "last-section" }

Environment

zk 0.15.2

It's probably best to use goldmark to parse markdown in the LSP the same was we do outside of the LSP.
