Rubric Editor API Events
practice:stimulus:render
Fires when the stimulus section within the Test panel is rendered and contains meaningful content.
You would want to listen to this event when you need to post-process specifically the stimulus content within the Test panel, for example, to trigger math rendering on the stimulus element.
Examples
rubricEditor.on('practice:stimulus:render', function () {
// Post-process the stimulus content, e.g. render math
MathJax.typesetPromise();
});
