Cursor sometimes skips empty paragraphs when moved with Up/Down keys (FF-only)

[kossebau]

How to reproduce:

1. welcome.odt
2. create a new paragraph after "It can embed fonts too"
3. put cursor with mouse at start of "It can embed..."
4. Press cursor-down key
5. Press cursor-up key
6. Goto 4 unless you managed to reach the empty paragraph (but break whenever you like :) )

Expected:
empty paragraph can be reached that way

Actual:
empty paragraph is skipped when the cursor is moved up/down.

It does not skip it if the cursor-up key is pressed when the cursor is in the paragraph below and at least in the text "give you access to your ..."

This is related to broken line detection code such as described in #224 , as well as FF incorrectly causing line wraps at the point of the cursor (#86).
