Let me rephrase since my example overstepped slightly, as Alex noted.

Example A:
<div style="margin:50px; width:50px; height:100px; box-shadow: 10px 20px 5px 10px blue"></div>

Example B:
<div style="margin:50px; width:50px; height:100px; box-shadow: -10px 20px 5px 10px blue"></div>

1. Render A
2. Take a screenshot of A
3. Render B
4. Take a screenshot of B
5. Flip the image of 4 horizontally

Must the box-shadow rendering from 2 match the box-shadow rendering from 5?
