Created attachment 98953 [details] Testcase In WebKit, calling endElement on an SMIL animation causes the animation to jump to the end state. In Gecko and Opera, it causes the animation to pause in place, without jumping to the end state. Steps to Reproduce: 1. Open the attached testcase. 2. Click the green button. 3. Click the red button. Expected Outcome: The circle stops moving and remains in its current location. Actual Outcome: The circle stops moving and jumps to the location it would be in had the animation run to completion. There is a significant disparity between the way [Opera, Gecko] and WebKit handle this.
