In Cilium we're using this action and hitting an issue with the rendered mermaid charts: cilium/cilium#32241 (comment)

After some investigation, I think we are hitting this bug mermaid-js/mermaid#2495.

Basically, if the telemetry action generates a chart with words like "call" in the node text, it breaks rendering due to the mermaid bug mentioned above.

Here's a minimal example that fails

gantt
	title Some title
	dateFormat x
	axisFormat %H:%M:%S

	Call blah blah blah : 1721689506000, 1721689507000

And it works if you remove call:

gantt
	title Some title
	dateFormat x
	axisFormat %H:%M:%S

	blah blah blah : 1721689506000, 1721689507000

I've actually never used mermaid charts myself yet, so I'm not sure how easy it is to fix, but according to mermaid-js/mermaid#2495 (comment) you can wrap the nodes in quotes to fix the issue?

So eg:

gantt
	title Some title
	dateFormat x
	axisFormat %H:%M:%S

	"Call blah blah blah" : 1721689506000, 1721689507000

Seems to work 🤷 . Maybe the action can be updated to quote everything to fix the issue?
