Arrow down from code cell to folded regions can unfold it

[rebornix]

Type: Bug

When we have a notebook with following structure

- code cell 1
- markdown cell header 1
- code cell 2
- code cell 3
- markdown cell header 1

• Fold markdown cell
• Put cursor in code cell 1's text editor
• Arrow down until it moves the focus to the markdown cell
• Arrow down again, it unfolds the region other than just navigates to the next markdown cell (header)
