This issue is a follow up of EZP-27253

Steps to reproduce

-Create one folder (don't publish)
-In one of richtext fields, click to create an embed content
-When UDW opens, click in "Create" tab
-Select "Article" object. -> Click "Next" button -> Click "Confirm Selection" button
-When the form to edit the article appears, we are placed on top of the article fields. This is the expected place to be.
-Fill in the mandatory fields and scroll down to the middle or to the end of the article (due the patch, we can now do this)
-Publish the article
-Now do it all over again, embedding another article (click to create an embed content -> -When UDW opens, click in "Create" tab -> Select "Article" object. -> Click "Next" button -> Click "Confirm Selection" button)
Now, when the form to edit the article appears, instead of being on the top of the form (as we were when we created the first embed article), we are now placed in the end of the form. To the user, this might be an unexpected.place to be.

Edit: Happens on firefox 52 but not on chrome
