User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.6; rv:25.0) Gecko/20100101 Firefox/25.0 (Beta/Release) Build ID: 20131112160018 Steps to reproduce: Open the attached file, hover the mouse over the circles. Actual results: 1) The CSS :hover is applied to the green circles, but not to the red circle. (The red was added for clarity of bug submission only, and does not affect behavior.) 2) When the CSS :hover is applied, the radius of the stroke increases. Expected results: 1) All circles should change when hovered over. 2) The radius of the stroke should not change. Only the stroke-width should change.

Tested both on Mac OS X and Windows XP.

Is this still an issue on aurora or beta or nightly firefox?
