When corner radius of a linear progress indicator is larger than 0, the behavior it's confusing because when the progress fraction is slightly larger than 0, the progress indicator will suddenly show with a width of twice the corner radius.
Fixes this by adjusting the indicator startX and endX correctly so the visible indicator length is always proportional to the progress.
