Line break in Markdown string is considered to be code block.

[RokeJulianLockhart]

subgraph s10["`**Nation 1**
	An external placeholder nation which exists to demonstrate that legally, alternate nations are able to exist outside the bounds of Nation 0. However, whether any alternative nation(s) should exist should be considered carefully.

	A sensible reason for such a nation to exist is physics constraints so severe that due to lack of ability to contact and/or provide physical assistance to the nation, it must govern itself. Expected inability to *ever* contact the other nation is a situation in which this applies, perhaps if it is travelling into space at a relevant pace and to a relevant eventual distance.`"]
end

s10 -.- |<i>Hierarchy| s3

subgraph s3["`**Nation 0**
	This is the nation which this document describes. It should be the most powerful nation economically and militarily in order to prevent invasion, in order to sustain its meritocratic and just institutions.`"]

		Provides administration to its ultimately separate subordinates.`"]

	subgraph s4["`**Product and Service Improvement Authority**
		Provides competition against, and mutually advantageous co-operation with, private organizations.`"]

		subgraph s6["`**Public Service Authority**
			To ensure healthy competition, a singular public entity would be established to compete with private companies. Subordinate entities would be created in a federal manner to compete in specific sectors such as food, clothing, and basic digital devices. The more specific the need, the more entities would be the entity's parent, unless its purview does not fit into the systems of the existent entities, in which case it could without problem be subservient solely to the ultimate parent despite being niche.

			This system aims to enhance affordability, quality, and customer service by fostering market competition, because whereas the private system when comprised of small companies is incapable of *not* innovating in the short term in order to survive, the government would take the role of traditional private monopolies, yet would instead use that power to slowly enhance the quality of its development systems and products by utilizing the innovations of the private sectors. It *would* improve due to its federal structure - accountability goes up the chain to the head of state, and consolidates those with similar interests into groups able to demonstrate their competence yet managed by those with broader visions. It's the standard system of competing interests, but properly managed.`"]

Suggested Solutions

Simply allow newlines. Markdown doesn't process them as indentation, even in indented lists:

1.	Placeholder
	
	Placeholder

Additional Context

This cannot be worked around using Markdown line breaks, because that reports "Unsupported Markdown: break". Additionally, https://github.com/orgs/mermaid-js/discussions/4575#discussioncomment-8586213 may be of note.
