Mermaid graphs not rendering at all on iOS

Bug reports
1

Steps to reproduce

  1. Install latest version of Obsidian on iOS.
  2. Create an empty new file and put in any mermaid diagram. For demonstration purposes, an empty one (ticks with “mermaid” and nothing else) works.
  3. Enable the reading view.

Did you follow the troubleshooting guide? [Y/N]

Expected result

I’d like to see the mermaid graph being rendered.

Actual result

One of the following always happens: (1) I see a blank diagram; (2) I see syntax highlighted source code of the mermaid diagram; (3) I see the error message “Error parsing Mermaid diagram! Can’t find variable: mermaid”.

By this I mean that I see a blank diagram even if the diagram source code is not empty.
