commit c831580e1b4547d5fcbe74864e657c1c4ebffc12
Author: Henrique Nakashima <hnakashima@chromium.org>
Date: Thu Apr 19 21:59:33 2018

Fix duplicated text in each line in XFA widgets.

When calculating the characters to display, the run offset was not
added to the offset inside the run, so characters from the first run
were always used instead of from the run that the line should display.
