Style sharing didn't play nicely with elements getting their display adjusted based off the parent's display. We style share without doing adjusting, so we need to avoid style sharing if adjusting would result in a different style. Particularly, we need to make sure that the display coercion would happen in the same way. R=esprehn@chromium.org Review URL: https://codereview.chromium.org/839153002
