[SPARK-11906][WEB UI] Speculation Tasks Cause ProgressBar UI Overflow When there are speculative tasks in the stage, running progress bar could overflow and goes hidden on a new line:  3 completed / 2 running (including 1 speculative) out of 4 total tasks This is a simple fix by capping the started tasks at `total - completed` tasks  I should note my preferred way to fix it is via css style ```css .progress { display: flex; } ``` which shifts the correction burden from driver to web browser. However I couldn't get selenium test to measure the position/dimension of the progress bar correctly to get this unit tested. It also has the side effect that the width will be calibrated so the running occupies 2 / 5 instead of 1 / 4.  All in all, since this cosmetic bug is minor enough, I suppose the original simple fix should be good enough. Author: Forest Fang <[email protected]> Closes #9896 from saurfang/progressbar.
