### Describe the problem The result of `main.to_docutils` include an extra newline in each `literal_block` node. ### Link to your repository or website _No response_ ### Steps to reproduce Script: ```python from myst_parser.main import to_docutils from docutils.core import publish_doctree doc = to_docutils("```\ncode\n```\n") print(doc, end="\n\n") ref = publish_doctree("::\n\n code\n\n") print(ref, end="\n\n") from docutils.core import publish_from_doctree print(publish_from_doctree(doc, writer_name="html4css1", settings_overrides={"embed_stylesheet": False}).decode("utf-8"), end="\n\n") print(publish_from_doctree(ref, writer_name="html4css1", settings_overrides={"embed_stylesheet": False}).decode("utf-8"), end="\n\n") ``` Output: ``` <document source="notset"><literal_block language="" xml:space="preserve">code </literal_block></document> <document source="<string>"><literal_block xml:space="preserve">code</literal_block></document> … <body> <div class="document"> <pre class="literal-block"> code </pre> </div> </body> </html> … <body> <div class="document"> <pre class="literal-block"> code </pre> </div> </body> </html> ``` Notice the extra newlines in the output of MyST (compared to the expected docutils output `ref`) ### The version of Python you're using 3.8 ### Versions of your packages MyST: 5fd4c51
