Description

According to documentation, it is possible to create a node with text using Markdown formatting in flowchart diagrams. To do this, the text should be enclosed in quotes and backticks "` text `".

However, it appears that text is being interpreted as Markdown even when it is not enclosed in quotes and backticks. This causes problems when trying to create nodes with text corresponding to unsupported markdown syntax, making it difficult or impossible to display certain texts as plain text in nodes. Examples:

• 1.
• - x
• 1. phase
• ...

Steps to reproduce

Creating the following diagram in Mermaid results in nodes with error messages instead of displaying the text:

flowchart LR
    a["1."]
    b["- x"]

Setup

• Mermaid version: 11.1.0
• Browser and Version: Chrome, Firefox

Suggested Solutions

• The text should be displayed as plain text in the node when it is not enclosed in quotes and backticks. The Markdown formatting should only be applied when the text is correctly enclosed.
• Add support for an escape sequence (e.g., 1\.) to prevent Markdown interpretation.
• Add an option to turn off Markdown formatting.
