I’m working on a web app that has a lot of tables. In the prior version of the product, there was a little extra padding on the table rows. This wasn’t defined specifically in a style sheet, but was added by the User Agent (Chrome in this case) as border-spacing:

In the new version, this spacing is gone– but I don’t see where it was changed. Now the user agent’s border-spacing is being overridden by table[Attribute Style] which is setting -webkit-border-n-spacing values:

Where is this table[Attribute Style] being defined, and why would it be different between the two versions when I’m using the same browser to view the same (basic) code?
