Table: arrow up/down should not always move selection to sibling cell

[zbeyens]

Description

Currently, arrow up/down in a cell will always move selection to sibling cell. We don't want this behavior when the next selection is still in the same cell, it happens when a block has multiple lines or when there is many blocks in a cell.

Steps

• insert and select a second block in a cell
• press arrow up
• it moves the selection to cell above
