Thank you for the pull request.

Could you reflect this change with a minimum description in the docs? I'm guessing this would be the right place.

Also, if possible, could we have a test for it? If it can't be unit tested (which I think it can't), you can create a new graph on /cypress/platform/. Those get checked for backwards compatibility on each build.

The documentation could be solved by adding a default setting in mermaidAPI.js with the corresponding api. Documentation will then be generated. Se corresponding setting for htmlLabels below:

  flowchart: {
    /**
     * Flag for setting whether or not a html tag should be used for rendering labels
     * on the edges.
     * **Default value true**.
     */
    htmlLabels: true,
