When creating or updating tasks via the API using markdown_description, extra vertical spacing (empty line) is added between different block types: heading to text, text to heading, text to bullet list, and bullet list to text. Consecutive bullet points and consecutive text lines render correctly without extra spacing. The same content typed manually in the editor does not produce this extra spacing. Confirmed with both direct REST API calls and the MCP connector, same behavior.

It would be useful to either fix this so the API renders the same as the editor, or provide an option/parameter to control paragraph spacing in markdown_description (e.g. a compact_markdown flag or similar).
