Undefined portal variable not catched propertly in editor

We have had an issue in our Evaluation System tool. When we use it in MyWorkspace, CKEditor doesn’t load because a javascript stacktrace is thrown.

Uncaught ReferenceError: portal is not defined

The reason is in ckeditor.launch.js file, where this code doesn’t catch propertly the undefined variable:

if (collectionId.startsWith('/user/') && portal && portal.siteId)

In the same file there are other places where the portal variable is checked, this is the way:

if (collectionId.startsWith('/user/') && typeof portal != 'undefined' && portal.siteId)

After this change everything keeps on working and our issue doesn’t happen anymore.
