Align to Pixel Grid & Lock Aspect Ratio in combination not working

"Align to Pixel Grid" option not respecting "Lock Aspect Ratio" in certain scenarios.

Steps to reproduce: 
1. Create a new Artboard, Add a circle

- Radius: 12.4 (Same height & width)

- Lock the aspect ratio

- Position: X: 12.2 Y: 12

2. Select the "Align to Pixel Grid" option.

Expectation: 

1. The shape should be resized to a radius without decimal value

2. The position should be adjusted to align with the grid

3. The aspect ratio should be maintained.

Actual Observation: 
Width : 13

Height: 12

Position: X: 12 Y: 12

The first 2 expectations are met, but the aspect ratio is not maintained even though the "Lock Aspect Ratio" option is selected.
