Description: There is a noticeable inconsistency in anti-aliasing when combining shapes with an outline in Adobe Illustrator.

Left Image (With Outline): Shapes with an outline are rasterized with a visible anti-aliasing effect.
Right Image (Combined Shape): After combining the shapes, the anti-aliasing effect appears smoother and more refined.
From my understanding, both images should exhibit similar anti-aliasing behavior when rasterized, as they are essentially the same shapes. However, the anti-aliasing in the first image (with outlines) is harsher compared to the combined result on the right.

Expected Behavior: Both shapes should be rasterized with the same level of anti-aliasing, regardless of whether the shape has an outline or has been combined.

Steps to Reproduce:

Create shapes with outlines in Adobe Illustrator.
Combine the same shapes using the "Pathfinder" or "Shape Builder" tool.
Rasterize both results and compare the anti-aliasing effects.
