Wrong tabindex in foreign key editor?

When you add a new foreign key in the table editor and use the TAB key to navigate through the different items you need to fill, after the "Columns" column you end up in the bottom panel (the one with the table columns). I'd expect to move to "Reference table" instead.

It works fine if I use the right arrow key but still it feels awkward that you cannot use TAB :-?

BTW, is it me or the grid in the foreign key editor behaves differently from other grids when you resize a column with the mouse?
