The icons that are inside the buttons that are placed to the right side of the control menu are not well aligned vertically. They seem to be 1px down.

Exception:
The eye button in portlet pages seems to be well aligned. This button is in the same group as the title.

So maybe there is some CSS modifying the vertical alignment a producing that side effect.

Please see the video.

Steps to reproduce:

• Go to pages
• Edit search pages
• There you have the full set of actions in the control bar
