Arbitrary deletion of multi-line cells containing markdown text

[irm-codebase]

Description

When requesting multi-line cells containing markdown text, sometimes a cell will register as empty in the diagram despite having the correct syntax.

Interestingly, this only seems to happen for the live editor and Github documentation.
It won't happen in the (unofficial?) VSCode extension.

Might be a duplicate of #5785, #5787, #5698

This case is slightly different, though, so I decided to create an issue.

Steps to reproduce

Paste the code sample in the live editor and look at cell O1.
It's a squashed square!

    M --> O2("`**Capacity**

        hydropower_storage.csv

Setup

• Mermaid version: v11.0.2 (as of creating this issue). I am not sure what Github is using.
• Browser and Version: Firefox 129.0.2 (64-bit) - Flatpak version

Suggested Solutions

Honestly, no idea. Might be a simple fix, since the diagram does not crash.
The context of the cell is probably erased at some point.

Additional Context

Have a nice day!

[irm-codebase]

latest version fixes this, so I'll be closing this issue!

Not sure of what fixed it, but it's gone.
