"<" symbol causes bad output with "uftrace dump --mermaid"

[Nor-s]

Describe the bug

"<" symbol causes bad output when using the "flowchart": {"htmlLabels": false} mermaid config option.

To Reproduce

// helloWorld.cpp
#include <iostream>

int main()
{
    std::cout<<"Hello World";
}

$ g++ -pg helloWorld.cpp
$ uftrace record a.out
$ uftrace dump --mermaid > ./tmp.html

Screenshot

tmp.html

Proposal

As a temporary measure, setting "htmlLabels": true

• mermaid.js issues: https://github.com/mermaid-js/mermaid/issues/4390

result: "htmlLabels:true"
