[Bug] Using the properties menu deletes YAML comments from the frontmatter

Steps to reproduce

  1. In source mode, add a property and a YAML comment to the frontmatter, like such:
# comment
  1. Exit source mode and go back into source mode. Nothing will have changed.
  2. Exit source mode and change the property by adding a value, such as a tag.
  3. Switch back into source mode

Expected result

Like in previous Obsidian versions, the comment should still be in the frontmatter

Actual result

The YAML comment has disappeared from the frontmatter

Additional information

This is a very recent bug. A few minor versions/weeks ago, I am very confident this wasn’t a problem yet.

The reason this bug is significant is that I need to add comments to the frontmatter to tell the Zotero integration plugin to “persist” my custom metadata. Thereby, it breaks the workflow of a number of academics like myself. More broadly, this bug may break the functionality of a number of plugins that rely on YAML comments to add additional information to the frontmatter.

I would be very grateful for a fix :smiling_face:


It’s not that recent.

Moved to help.

ok thanks! Didn’t find the the thread below. Even if it’s not recent, I am confident it happened a bit after the introduction of Properties. While I understand the desire to expose a clean API, it would be great if comments are preserved because that would otherwise mean breakage for a number of template engines when they interact with the frontmatter.
