With the MarkdownEditing package installed, an extra backtick is left when creating a code block as seen here: https://github.com/SublimeText-Markdown/MarkdownEditing/assets/10835824/824464ff-fe2a-423a-8a98-d6cacce7185c Without the package, the native behaviour is to remove the closing backtick when more than two are inserted: https://github.com/SublimeText-Markdown/MarkdownEditing/assets/10835824/6b086140-3cc4-4232-93a7-fef83fac6a16 I would argue that the native behaviour is the expected/preferred one.
