Useless re.sub in format_markdown?

[99991]

Is the second re.sub in format_markdown doing anything useful?

zerox/py_zerox/pyzerox/processor/text.py

Lines 7 to 11 in aa3d881

	def format_markdown(text: str) -> str:
	"""Format markdown text by removing markdown and code blocks"""
	formatted_markdown = re.sub(Patterns.MATCH_MARKDOWN_BLOCKS, r"\1", text)
	formatted_markdown = re.sub(Patterns.MATCH_CODE_BLOCKS, r"\1", formatted_markdown)

zerox/py_zerox/pyzerox/constants/patterns.py

Lines 4 to 6 in aa3d881

	MATCH_MARKDOWN_BLOCKS = r"^```[a-z]*\n([\s\S]*?)\n```$"
	MATCH_CODE_BLOCKS = r"^```\n([\s\S]*?)\n```$"

MATCH_MARKDOWN_BLOCKS matches any markdown blocks with an optional language specifier after the first three backticks, while MATCH_CODE_BLOCKS only matches markdown blocks without language specifier, so the later should allready be included in the former, or am I missing something?
