This is a followup issue from https://bugs.openjdk.org/browse/JDK-8207333

To reproduce: using the monkey tester (or any other application with a a table view with reorderable columns):

- start dragging a column
- while dragging, richt-click to invoke the context menu
- observe that the column highlight jumps back to the initial position, decoupling itself from the cursor

This does not happen on macOS (please check Linux).

I might recommend to change the behavior of right click when dragging, to make it work just like JTable - instead of showing the popup, complete the reordering operation.
