Summary: Overlay scrollbar flashes when navigating to unscrollable page. (was: Regression: Blink of unwanted vertical scrollbar is seen in About Chrome OS page of Chrome://md-settings.)
Not a regression as these are new overlay scrollbars. The scrollbars show whenever the content size changes. We can probably tweak the behavior to be better / not show when they're unneeded.
