Remove the if statement, just call updateStyleIfNeeded() unconditionally.

The renderer() is non-null here with this CL.  That will change what is drawn in
the document.title, right?

         if (size.width()) {
             // Compute the title, we use the decoded filename of the resource, falling
             // back on the (decoded) hostname if there is no path.
             String fileName = decodeURLEscapeSequences(document()->url().lastPathComponent());
             if (fileName.isEmpty())
                 fileName = document()->url().host();
             document()->setTitle(imageTitle(fileName, size));
