When clicking slider lines in Chrome in RTL the pointers move to the wrong position. Also browsing with the arrows seems to be broken there and is not really working.
This only seems to happen when the slider shows a part of the history where you can load more revisions to the left and right. See example link:
The bug seems to be related to wrong position numbers on the revisions. They seem to break when new revisions are loaded in the initial load to fill the screen. This also affects the grayed revision bars that mark the range of the selection. As seen in the screenshot there is an offset between the pointer positions and the grayed revisions. When the browser window is resized and the slider renders fresh, the positioning is fixed.
A rough backtracing of the bug revealed, that it already occurs long before we introduced the new sliding mechanism - so it seems no one noticed so far. (?)
Broken in all Chrome V8 engine browsers
