Dynamic scroller has potential performance case

[Matrixbirds]

Clear and concise description of the problem

I'm using DynamicScroller in CEF M99. It will become janky with many pictures resource in DynamicScrollerItem in extremely scrolling case.

Suggested solution

I think probably there is some calc task will block the render processing, it will cause dropping frame with white gap rendering empty content while scrolling.
