Open any form with TinyMCE editor
Make sure the button 'Manage files' appears after button 'media' or 'image' (if media is not present)
Try changing TinyMCE button layout, make sure the 'Manage files' and repeat the test
This issue links MDL-28019 and MDL-40648 because I submit both of them at the same time and don't want them to depend on each other in integration.
Make sure that 'managefiles' button in TinyMCE is located after 'media' or 'image' button regardless of their button row.
