- Light themes: the appearance, shape picker, icon picker, and sample picker popups render their grids and toolbars on the popup surface instead of a mismatched background
- The shape picker no longer shows a stray partial separator under the category tabs; a single full-width separator remains
- Light themes: the hover highlight on the icon, shape, and appearance tile grids now stands out clearly
