Before this commit, when adding a icon to a statusbar button, there was no margin between icon and text. This makes button not very nice as button is very near to the text itself. After this commit, for readability purpose, a margin has been added to the icons of a statusbar button. Statbutton margin has been chosen to keep things coherent through form buttons.
