• Go to a site, and create a fragment collection, so that you can see the empty collection interface
• Switch to a RTL language by prepending ar/ in the beginning of the URL path
• Page is displayed RTL.
• Click on all kebab menus and '+' icons available in the page

 Observed: Some menus appear below and to the right of the icon you click (product menu, collection options). Others show the options at the top-right side of the screen, very far away of the clicked icon. That is the case of the "+" button to add a new fragment, and the collections menu (Import, Export, Delete).

 Expected: all contextual pop-up menus appear "mirrored" respecting the LTR rendering, that is, below and to the left of icon user clicks.
