Using the per-revision bisect providing the bisect results,
Good build:61.0.3132.0(Revision:479900).
Bad build:61.0.3133.0(Revision:480259).

You are probably looking for a change made after 479930 (known good), but no later than 479931 (first known bad).

It's my patch, but issue seems minor so I'm not planning to work on it for 61.

The scrolling gets stocked since clicked element is removed from DOM.
