Proposed fix for #303765:

Root cause was due to the #isScrolling flag that tried to prevent scroll feedback loops. Whenever the scrollTo() function was called while the flag was already true, it would return the cleared flag early and cause the jumpiness seen before.

Added a public isScrolling() function in order to prevent scroll events that occur from the preview to be echoed in the monitor.
