Created attachment 8483854 [details] first-line bug.PNG User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/37.0.2062.102 Safari/537.36 Steps to reproduce: 1) Go to http://benhowdle.im/cssselectors/ 2) Select "first-line" (left-hand menu) Actual results: The first line of <p> tags don't change to green. As you can see in the attached screenshot, Firebox (in Firefox) is showing that the green *should* be applying, however, it's not. Expected results: The first line of <p> tags should change to green. There's a way to force Firefox to color the first line green: 1) Add an element style to the <p> tag 2) Change the <p> to display: block -- notice that this does *not* fix the issue 3) Change the <p> to display: inline-block -- this fixes the issue (the first line is now green) 4) Change the <p> back to display: block -- the first line remains green.
This is also broken on Nightly. Not sure if this is css computation or layout (esp. considering switching display: about fixes things), but leaving this here for now.
