There are 2 problems with styles of right sidebar in Safari:

• Translated title of dashboard doesn't fit to width of sidebar. For some reason space doesn't work as break line. (in safari, chrome)
• For "Add" and "Edit mode" buttons different html code is used. And as result icon is not in the centre of button. On the screenshot I did hovering specially to make it visible. Also if I click on the side of "Add" button, it doesn't work. (in safari)
