If wikitext contains several empty lines in a row, hovering over those lines in the VisualEditor will present them as uneditable elements. Since the VisualEditor is perfectly able to create and remove empty lines, this seems unnecessary.
This has been fixed (by removing the mwPlaceholder code in Parsoid, now that VisualEditor can handle these). Sorry for not responding before.
