Visual: notification icons are the odd one in the header with most skins. Bit misaligned or over-sized, different focus outline (and slightly transparent).
Technical: changing alignment (margin, padding, font-size) of menu items in the header is very likely to change positioning of the notification icons in significantly different ways than menu items. The icons should behave consistently with menu items.
- Notification button sizes are proportional to the header and menu items (Modern, MonoBook).
- Button sizes are responsive to font-size changes (all skins).
- Buttons' focus outline can be restored to browser default, consistent with any other link's behavior (all skins).
