Increase extra small preview size from 8px to 12px
In the SVG Previewer configuration menu 8px is the extra small option. This change would increase that to 12px. There aren’t any icons created on an 8px grid, but there are some, like the severity icons, that are created on a 12px grid, and in the future there may be more. This allows a user to view the icons at the authored size, and not just a ratio of the default 16px grid.
