I don't have review permissions, but I'd like to comment on something that caught my eye.

The following image is a screenshot of the test `test/jdk/javax/swing/JMenuItem/TestRadioAndCheckMenuItemWithIcon.java` that was added by [JDK-8348760](https://bugs.openjdk.org/browse/JDK-8348760).

Before

After

Before this change, the left edges of all the red squares are aligned, and the text of each menu item is also left-aligned.
However, after this change, for menu items without radio buttons or checkboxes, the red squares and the text are misaligned compared to the others.
Is this an expected behavioral change introduced by this fix?
