The links do not work (seems all clicks are prevented)
https://jsfiddle.net/7jes49g0/
The column content does not have to be long. Seems the behavior here is that if we click on partially visible column HOT scrolls to the start of the column to make this column fully visible, but in case when column width is larger than the table size, the column will be still partially visible after scrolling and clicks are still ignored. Hope it will help to track down the issue.
And there is more. If I fix columns to the left, leaving just that long column in the scrollable area - NONE of the links will work
