Steps to reproduce the problem:
1. Wrap a table in a container with overflow: auto
2. Add box-shadow to a <td> within the table that will "bleed" outside the container
3. The container shows a scrollbar so you can scroll to see the rest of the dropshadow

What is the expected behavior?
Box-shadow should not influence scrollbar behavior

What went wrong?
Box-shadow should not trigger scrollbars if they bleed outside the parent

Does it occur on multiple sites: Yes
