SHIFT-UP does not work as expected

SHIFT-UP does not work as expected, but I'm not sure if it has something to do with Anchor support that was recently updated.

ListView
- click e.g. Row 10 and press SHIFT-UP
- RESULT: Row 1-Row 10 becomes selected
- EXPECTED RESULT: the selection will be extended up by one item, thus Row 9-Row 10 will be selected
- note that there is no issue with pressing SHIFT-DOWN

TableView
- click e.g. 10th entry
- press SHIFT-UP
- the selection is extended by one item up
- press SHIFT-UP again
- the selection is extended by one item up, but the 10th item becomes deselected
- RESULT: only two entries are selected all the time, the selection is moving up
- EXPECTED RESULT: the selection will be extended up by one item.
- note that there is no issue with pressing SHIFT-DOWN
