This looks like it's duplicating what Frederic was trying to do in bug 182785. You need to be careful here; this change can affect both UIWebView and WKWebView on iOS, and you need to examine the callers to make sure you didn't break anything. Also bear in mind that we don't have good UIWebViewtest coverage.
