Dialog button focus is misshapen

Dialog button focus is misshapen

Using the latest Chrome in Windows 10, any jQuery UI Dialog box close buttons (the default X in the upper right corner) have a screwed up focus shape. See below.



This not only happens on my own dialog boxes, but also the preview ones on jQuery UI's site, so I know it's not an issue with the implementation on my site.

Does anyone know what may be causing this?
