When a timeline view with several lines is displayed and if we scroll down the page (for example on smaller screens) to reach timeline items that are down then the mouse select drag is totally uncentered. It selects several lines higher than the one we are pointing.
The more we go down on page the more misaligned is the timeline item select event compared to mouse.
Hope you understand. I don’t know how to make a screenshot of that as the mouse pointer is not captured.
Grab the updated build ( attached ) - it must fix the issue with invalid event position in IE
