Content-Aware Crop modifies pixels inside original image bounds

Expected: Content-Aware Crop should use pixels from the original image as sampling material, but only generate/fill pixels in the newly expanded canvas area.

Actual: In Photoshop 27.9.1, Content-Aware Crop also modifies and blends pixels inside the original image bounds. This can distort products/models near the crop boundary. In professional retouching this is destructive because original product pixels must remain unchanged.

This behavior appears to have changed after a recent Photoshop update. Previous versions did not modify the original image area in the same workflow.
