   I noticed that new snippets created using v5.5.0 are using 3 backticks as the container format again, instead of 4 backticks. Was this an intentional change?

   I've seen the issue occur a couple of times with snippets I created new in v5.5.0, but haven't figured out how to reproduce it. Is it possible that new snippets which are using the 3 backticks are still triggering the issue sometimes? Even with old snippets it doesn't happen every time. It's a bit random.

   Could you check whether the affected .md snippet and nearby snippets have duplicate contents[].id values in frontmatter?

   The 3-backtick fence itself does not look like the issue in v5.5.0. The serializer now chooses a longer fence when the content contains backticks.

   Example:

   contents:
     - id: 1

   Yes, several snippets in the same folder have the same contents block in the .md

   contents:
     - id: 1
       label: Fragment 1
   

   The id: outside the contents block is different for each one, though.

   I duplicated each snippet and deleted the original to fix the duplicate id: values.

   Thanks for checking. That confirms the likely cause.

   The update path currently resolves fragments by contentId globally. With duplicate contents[].id values, an edit can hit the wrong fragment and then look like a revert after sync.
