Guidelines for icons in segments

<SegmentedControl aria-label="File view">
  <SegmentedControl.Button defaultSelected aria-label="Preview" leadingIcon={EyeIcon}>
    Preview
  </SegmentedControl.Button>
  <SegmentedControl.Button aria-label="Raw" leadingIcon={FileCodeIcon}>
    Raw
  </SegmentedControl.Button>
  <SegmentedControl.Button aria-label="Blame" leadingIcon={PeopleIcon}>
    Blame
  </SegmentedControl.Button>
</SegmentedControl>

<SegmentedControl aria-label="File view">
  <SegmentedControl.Button defaultSelected aria-label="Preview" leadingIcon={EyeIcon}>
    Preview
  </SegmentedControl.Button>
  <SegmentedControl.Button aria-label="Raw" leadingIcon={FileCodeIcon}>
    Raw
  </SegmentedControl.Button>
  <SegmentedControl.Button aria-label="Blame" leadingIcon={PeopleIcon}>
    Blame
  </SegmentedControl.Button>
</SegmentedControl>
