User Agent: Mozilla/5.0 (Windows NT 10.0; rv:58.0) Gecko/20100101 Firefox/58.0 Build ID: 20170923100045 Steps to reproduce: Example document: `<!DOCTYPE html><html><body> <div data-text="World">Hello</div> <style> div::after{ content: attr( data-text ); } </style></body></html>` Actual results: With Stylo enabled (`layout.css.servo.enabled`): - the text reads "Hello" and a "Declaration dropped" warning for the `content` value is sent to the Console. - with the spaces around the attribute name in `attr()` removed, the text reads "HelloWorld" and no warning is given. With Stylo disabled, the text reads "HelloWorld" and no warning is given. In other tested browsers (IE 11, Edge 38, Chrome 61), the text reads "HelloWorld". Expected results: I couldn't see the correct behavior detailed in the brief look I gave the spec, but this is a change from what Firefox used to do, and what IE, Edge and Chrome currently do.
