    Fix bug #9040: In RtL documents end-of-paragraph marker shifts the row 
display
    
    The fact that the bug was still present in the features/str-metrics
    branch comes from a goof in the initial implementation of 'virtual'
    row elements (completion and end-of-par markers). Now that this is
    corrected, everything works as it should.
    
    The fact that the bug is present in master is due to some other reason
    that is not useful to investigate now.
