When Jenkins is hosted on a subdirectory, as https://www.example.com/jenkins/,

curlori.js is not loading, I get a 404, fetching on https://www.example.com/plugin/echarts-api/js/culori.min.js instead of fetching on https://www.example.com/jenkins/plugin/echarts-api/js/culori.min.js.
In the html source :
<script src="/plugin/echarts-api/js/culori.min.js" type="text/javascript"></script>
and the others, view-model by example : 
<script src='/jenkins/adjuncts/f848dd8e/io/jenkins/plugins/coverage/metrics/steps/CoverageViewModel/view-model.js' type='text/javascript'></script>.
Then, culori is not defined when plugin is loaded on view-model.js. The error is visible on the web console.
