[text-box-trim] Fix when there is an initial-letter
text-box-trim is supposed to trim all parts above the point
specified by the text-box-edge. This patch fixes initial
letter boxes preventing the trimming, similar to
crrev.com/c/5539108 fixed for the Ruby annotation.
This patch has no behavior changes as the changes are under a
runtime flag.
