Select first/last clears anchor information - MultipleSelectionModel

Question

I have table with table.getSelectionModel().setSelectionMode(SelectionMode.MULTIPLE);. I need to implement go last/first row of a TableView. I used table.scrollTo(ind); table.getSelectionModel().clearAndSelect(ind). This would scroll to first row and select it. But If I try to select numerous rows (using mouse right button with + SHIFT) It doesn't select range of rows between first row and the one pressed but it simply set anchor at the selected row.

What I've observed so far:

1. From pseudoclass css information. First row is selected,focused - which is exprected.
2. table.getSelectionModel().selectedIndexProperty() table.getSelectionModel().getSelectedIndices() shows 0 and [0] respective - which is expected
3. Row is not really selected - table is no longer focused so I got grey not blue row. But even if I call table.requestFocus() at any time and use PlatformUtil.runLater() It doesn't change anything. So I assume this has nothing to do with table focus.

Any Ideas howto (from code) select first row and make such situation that after pressing mouse button on other row with SHIFT I got multiple selection?
