Working on a Symfony 2 project in development environment, I noticed that the Symfony debug bar appears correctly with all browsers except for IE8. It seems like the CSS for the bar is not loading properly in IE.
Upon further investigation, I found that the issue arises from version 2.0 onwards (including 2.1 and 2.2). Could it be possible that the web debug bar's CSS is utilizing CSS3, which would be an unusual oversight for Sensio Labs? I find it hard to believe.
