This bug causes LayoutTests/fast/text/find-kana.html to assert in the following way: When a find is *successful* on a string with U+0300 character, chromium updates the selection and Font::selectionRectForComplexText(run, point, height, from, to) is called with run={length: 3, ...}, from=0, to=3, but the TextRunWalker walker(run) gets normalized so that walker={length: 2}, from=0, to=3, and we essentially hit an out-of-bounds problem when working with the walker. I think the correct fix is to not normalize in this case; I will submit a patch for this.

The normalization was added by Yusuke with my review (in r47922). (bug 28742). The patch looks ok, but I'm not sure.
