      At https://REDACTED/jenkins/job/REDACTED/job/master/327/testReport/history/, if I comment out the $('[data-toggle="tooltip"]').tooltip(); call that causes JENKINS-64585, then Microsoft Edge developer console shows the following:

      I suppose it means the DOM has not yet finished loading when EChartsJenkinsApi.renderZoomableTrendChart tries to find "test-duration-trend-chart" by ID.

      The error does not occur if I make the entirety of history.js wait for the DOM, like this:

      jQuery3(function ($) {
    ...
});

      (This caught my eye while I was trying to find what causes JENKINS-64586.)
