ODT file showing cursor gets stuck in the start of page 2

Description:
When moving the text cursor using up and down arrow keys, sometimes the cursor gets stuck. Looking inside the attached example shows that it happens when soft page break is exactly at the actual page break.

Steps to Reproduce:
1. Open attachment
2. Press and hold down to reach end of the document
3. Press up to move back to the top

Actual Results:
The cursor gets stuck in the last page. Note that the cursor should be adjacent to the right side of the document. This should happen when you press and hold down arrow, then press and hold up arrow.

It happens exactly near <text:soft-page-break/> in content.xml, which matches the point where the page breaks.

One other observation is that if you go to the end of first line in the last page and press up, the cursor oscillates between the beginning and the end of this line. 

Expected Results:
The text cursor should move to the top of document when holding the up arrow.
