Mermaid Diagram isn't working

I have a mermaid diagram defined in my project’s README.

Source is below

graph TB
    subgraph sg_sf["SpecFlow"];
        sg_sf_dn("PlayNicely.SpecFlow.DotNet") --> sg_sf_exe("PlayNicely.SpecFlow.Executor")
    end

    subgraph sg_exe["Execution"];
        sg_exe_dn("PlayNicely.Executor.DotNet") --> sg_exe_exe("PlayNicely.Executor")
    end

    subgraph sg_prj["Projects"];
        sg_prj_prj("PlayNicely.Projects")
    end

    sg_sf_dn --> sg_exe_dn
    sg_sf_exe --> sg_exe_exe
    sg_exe_exe --> sg_prj_prj

But when rendered in gitlab.com, in Edge and Chrome, none of the text is rendered.

This is the project

And this is what gets rendered.

Hello, i have the same Problem in my project wiki. Mermaid Diagrams included into ascidoc. But i have not changed anything the last weeks… do we need to modify font color or something?
greetings, Mario

I wonder if it was transient? Or did you fix something? I’m seeing this

Seems to have been transient, it appears to be fixed now.
