That's right! The `ImageIcon` was painted instead of bullet or check-mark.

Now that you moved the `ImageIcon` to the right, the bullet or check-mark has to be painted where the bullets and check-marks are painted when there's no custom icon.

That's what I meant — the previous location of the bullet / check-mark should be preserved.

This is why I say that the layout and therefore the width of the menu item has to be updated.

Previously, the custom icon was painted over, or instead of, the bullet or check-mark.

This PR proposes painting the custom icon separately, which means the width of the menu item has increase to accommodate the margins around the custom icon as well as the icon itself.
