Page show strange when use scrollTo function

I want to click the status bar and call $$('.page-content').scrollTo(0, 0, 1000) to scroll my page to top, It can run.
But when I scrolling the page, and then I click the status bar to call $$('.page-content').scrollTo(0, 0, 1000), the page UI have some strange.
Is there anything else I can do?

you are not sharing enough info for us to help you.

Can you share a screenshot/video of the “strange” UI?
Or even better, make a fiddle with the error/bug.
