Preconditions:

1. Liferay DXP 7.0 with FP[89,90,91]
2. Liferay DXP 7.1 with FP17

Steps to reproduce:

1. Configure Liferay for using CKEditor editing web contents, so add following property to portal-ext.properties file:

   editor.wysiwyg.portal-impl.portlet.ddm.text_html.ftl=ckeditor
   

1. Add a new web content. In content area, CKEditor is showed.
2. Write some text and select it. E.g. 'Testing link'.
3. Click on 'Link' button on CKEditor's bar. A pop-up is displayed.
4. Click on 'Browse Server' button.

Expected behavior

• A Liferay pop-up is displayed over CKEditor's one to select a file.

Observed behavior

• A Liferay pop-up is displayed behind CKEditor's one. Liferay pop-up cannot receive focus, so is not possible to select any file.
