Created attachment 799852 [details] FF bug 2013-09-04.html User Agent: Mozilla/5.0 (Windows NT 6.3; WOW64; rv:26.0) Gecko/20100101 Firefox/26.0 (Beta/Release) Build ID: 20130903030201 Steps to reproduce: http://jsfiddle.net/Rw3GK/ Create a link with a substantial padding and inverted margin. The intended effect is to give anchors a larger hitbox for touchscreens, and this is achieved on all layout engines but Gecko. Actual results: Text always wraps in on itself, as the element is properly sized to its content, THEN given the padding and negative margin. Expected results: as in Trident, Blink, WebKit, and Presto, the text does not overflow.
The issue is with the right margin not affecting line-breaking; if only left margin styles are used things fit. David, what layout is the one the spec requires here, if any?
