Flowchart: Link text beginning with lowercase 'o' causes flowchart to break

[ssurve]

E.g.: <div class='mermaid'>graph LR\n\tstep0(step0)--next-->step1(step1)\n\tstep1--next-->step2(step2)\n\tstep2--next-->step3(step3)\n\tstep3--ok-->DONE((DONE))</div>
results in this output:

Uppercase 'O' works as expected:
code: <div class='mermaid'>graph LR\n\tstep0(step0)--next-->step1(step1)\n\tstep1--next-->step2(step2)\n\tstep2--next-->step3(step3)\n\tstep3--Ok-->DONE((DONE))</div>
output:

Is this a parser rule? Not starting a link text with lowercase 'o'? If yes, are there any more such rules? Please point me to the relevant documentation.

Thanks.

I can reproduce the issue:

This does work:

I find a workaround:

Put the link text inside double quotes then it can have any characters.

I still think it is a bug. I will dive into it whenever I have some time.

--o is a special syntax for ARROW_CIRCLE. I don't have any good solution for this behavior. I recommend the workaround above.

Or just use space step3 -- ok -->DONE((DONE))
