Research direction
Reproduce the bug using the provided jsfiddle (http://jsfiddle.net/k11e670p/) in Internet Explorer with strokeWidth=7. Investigate the progressbar.js source code to understand how strokeWidth affects the animation. Look for any IE specific bugs in SVG animation handling, possibly in the library's shape parsing or animation logic. The fix might involve rounding or clamping strokeWidth values.
