 Our bug tracker utilizes several labels to help organize and identify issues. Here's what they represent and how we use them:
 
-- `browser bug` - Issues that are reported to us, but actually are the result of a browser-specific bug. These are diagnosed with reduced test cases and result in a issue opened on that browser's own bug tracker.

 - `css` - Issues stemming from our compiled CSS or source Less files.
 - `customizer` - Issues with our web-based Customizer.
