Timeline Double Scrolling

Is anyone else seeing an issue with double-scrolling in Timeline after the 6.18 SFDC Release last week? This doesn’t appear to be impacting all CSMs (yet) however, I’ve had 2 reports so far that a 2nd scroll bar appears within Timeline and subsequently the main view only shows 2 entries at a time. The users have checked multiple customers and multiple browsers and I can confirm that I am not seeing the same thing in the same version.
