Parsing flowchart subgraph with external link is broken

[d33bs]

Description

Thank you for the great work on this project - it's fantastic to use! I noticed that when using flowcharts and specific nesting of nodes, specifically with a node id of manager (but also perhaps others) that a syntax error occurs. I imagine but don't know for sure whether this occurs due to the use of reserved keywords. In the example below, if I remove the id manager and change this to seemingly anything else, for example, mermaid, the syntax error no longer occurs.

Steps to reproduce

See the following mermaid.live link or use the following to reproduce this error.

flowchart LR

  memory
  code
  subgraph interpreter
    subgraph manager
        broken
    end
  end

code --> interpreter
manager <--> memory

Screenshots

Code Sample

See above.

Setup

• Mermaid version: 10.6.1
• Browser and Version: Chrome

Suggested Solutions

• Perhaps this is due to certain sequences of reserved keywords (I'm unsure). If this is the case, perhaps a page within the documentation outlining what is reserved or not might be helpful (if this doesn't already exist!).

Additional Context

Thanks again for any help you can provide!

This is not a case of reserved keywords (if you change manager to something else in both places, it still breaks).
It's a bug with subgraphs that have external links.

Thank you for the reply and clarification @sidharthv96 !

Hi I believe this has been fixed by #5127, it is still awaiting review but if you go over there and paste the flowchart code from this issue into the deploy preview it should work.

version 10.8 works.
