Incorrect/offset nearest-neighbor scaling when using Resize dialog

Hi, I've noticed that when scaling images down using nearest-neighbor, the pixels it samples from are offset when using the Resize dialog versus using Move Selected Pixels, particularly causing pixel art to be far blurrier when using Resize (especially when the initial size is not a multiple of desired size):

Is this behavior a bug? I've tried rescaling this same image in some other programs/libraries like ImageMagick and PIL and they worked fine, producing the exact same result as Move Selected Pixels, so I assume Resize is producing incorrect results here.

For Resize:

- Open Resize dialog, enter 256x192 as the desired pixel size and hit OK

 

For Move Selected Pixels:
- Select the tool and set Quality to Nearest Neighbor
- Manually scale the image by dragging it down to 256x192 in size
