FF produces an invisible selection upon a single mouse click into empty space between paragraphs. This selection prevents an intended click-hold-move selection.

Reproducible: Always

Steps to Reproduce:
1. open url, double left click at the first "unfehlbare"
2. single left click right above the selection
3. left click and hold button, move mouse into paragraph
Actual Results:  
· A document icon appears which moves with the mouse pointer.
· "<span class="topo_col main_col" id="hauptspalte" role="main"><p></p></span>"
  appears in the clipboard.

Expected Results:  
· Paragraph becomes selected upto the current mouse pointer position.
· No markup appears in the clipboard.

3.5 and 3.6 work OK. Additionally both do not display an empty line after the bold (H6) headlines and the successive paragraph (P).

> Actual Result: The grey bar moves.

This is no longer the case with rev. 6f998cc964be. Actually, selected objects seem no longer to move.

After a restart reproduction of Comment 6 fails. The bar moves.

ESR 17.0.7: fail
Firefox 28 works as expected.
