    tdf#164098 sw: Fix word overflow kashida justification crash
    
    This change fixes an infinite recursion crash while updating kashida
    insertion positions. This crash could occur if a word is too long to fit
    on a page and is broken onto another line, with the best-fit valid
    kashida insertion position on the previous line, and the following line
    also containing valid kashida insertion positions.
