Mermaid Integration: Gantt diagrams - compact display mode does not work

Gantt diagrams in Mermaid have a display mode that puts all activities on a single row called compact display mode. This is a good workaround until Mermaid timelines are implemented/supported. Unfortunately, compact mode does not work.

Steps to reproduce

  • Create a gantt diagram using Mermaid
  • Set the displayMode to compact
---
displayMode: compact
---

gantt
    title A Gantt Diagram
    dateFormat  YYYY-MM-DD
    section Section
    A task           :a1, 2014-01-01, 30d
    Another task     :after a1  , 20d

Expected result

  • Compact display mode should work as per the documentation

Actual result

  • DisplayMode has no effect whatsoever
  • Diagram is displayed correctly, no obvious error, compact mode line is simply ignored

Additional information

As should work:

As is displayed in Obsidian:

We don’t support this. It may also be a new feature of mermaid.

Would you consider supporting this? It’d be pretty useful and the base implementation for the Gantt is already there.
