In a TableView, a shift-click to select multiple items doesn't work if the second click is done on a different column than the first one.


To give you an example, the following code creates a TableView with two columns ("First Name" and "Last Name") and three items ("Person"s with "firstname" and "lastname"-properties).

Since 8u40, if you click on the "firstname" of the first item ("FirstName1") and then try to multi-select all by shift-clicking on the "lastname" of the third item ("LastName3"), all items are unselected instead of being selected.
On the other hand, shift-clicking the "FirstName3" after clicking "FirstName1" does work as intended.
