The SVG engine fails to render properly (on the 15-09-2008 nightly build for Windows) when I try to change the attributes of fill on a mouse over event, it also awkward render a path element when changing it's 'd' attribute on a mouse move event (like grabbing something on the screen and sliding it to alter the overall draw). An image of the problem can be seen at this URL: http://hm11.webraska.com.br/testes/piva/webkit_bug.gif
We need a test case otherwise this bug isn't actionable. Closing. Please re-open if you have an example SVG which fails to render correctly.
