This seems like it could potentially cause issues in the future. If we add
something to reset at the end of the loop but forget to add here.  Can we
re-structure this a bit so we don't continue? Set a flag and skip the remaining
work other then cleanup if the flag is set?

                             continue;
                         }
 
                         setLogicalHeight(lineBox->lineBottomWithLeading());
                     }
                 }
             }
         }
