Context not set correctly when navigating back to dashboard after workflow completion

When completing a workflow task, Web UI updates the tasks list and does a refresh, which will browse to the last document you navigated (navigating to a task which displays a preview of the document doesn't count), or go to the dashboard if there is no record of a last document. When landing back at the dashboard, the context is not set correctly, resulting in relative urls causing 404 errors. This includes favicons (e.g. /nuxeo/images/touch/favicon-16x16.png which should be /nuxeo/ui/images/touch/favicon-16x16.png), and any other assets that may defined on a custom dashboard e.g. images such as <img src="images/asset.jpg"/> become /nuxeo/images/asset.jpg instead of /nuxeo/ui/images/asset.jpg

I noticed that window.location.pathname = /nuxeo/ui when navigating back to the dashboard, when usually it is /nuxeo/ui/ which may explain why the urls are resolved relative to /nuxeo instead of /nuxeo/ui, perhaps?

Custom dashboard images can be "fixed" (worked around) by using absolute pathnames e.g.

<img src="[[_getImageUrl('asset.jpg')]]"/>
...
      _getImageUrl: function(name) {
        if (name) {
          var base = window.location.pathname;
          // Trim possible trailing slash
          if (base.endsWith('/')) {
            base = base.substr(0, base.length-1);
          }
          return base + "/images/" + name;
        }
      },

but the favicons (in login.jsp and ui/index.jsp) are not configurable through Studio.

The context (e.g. String context = request.getContextPath(); in login.jsp) needs to be fixed.
