+
+            * platform/ios-simulator/TestExpectations:
+            * platform/ios-simulator/ios/plugin/youtube-flash-plugin-iframe-expected.txt: Updated expected result based on the

+            * platform/ios-simulator/ios/plugin/youtube-flash-plugin-iframe-no-height-or-width.html: Modified to check the
+            width of each embedded YouTube video to ensure that we respect it (if specified).
+            * platform/ios-simulator/ios/plugin/youtube-flash-plugin-iframe.html: Substitute pseudo id -webkit-plugin-replacement
+            for -apple-youtube-shadow-iframe as the later was renamed to the former in &lt;https://trac.webkit.org/changeset/168442&gt;.

+            REGRESSION: Plugin replaced YouTube Flash videos always have the same width
+            https://bugs.webkit.org/show_bug.cgi?id=159998
+            &lt;rdar://problem/27462285&gt;
+
+            Reviewed by Simon Fraser.
+
+            Fixes an issue where the width of a plugin replaced YouTube video loaded via an HTML embed
+            element would always have the same width regardless of value of the width attribute.
+
+            For YouTube Flash videos the YouTube plugin replacement substitutes a shadow DOM subtree
+            for the default renderer of an HTML embed element. The root of this shadow DOM subtree
+            is an HTML div element. Currently we set inline styles on this &lt;div&gt; when it is instantiated.
+            In particular, we set inline display and position to &quot;inline-block&quot; and &quot;relative&quot;, respectively,
+            and set an invalid height and width (we specify a font weight value instead of a CSS length value
+            - this causes an ASSERT_NOT_REACHED() assertion failure in StyleBuilderConverter::convertLengthSizing()
+            in a debug build). These styles never worked as intended and we ultimately created an inline
+            renderer (ignoring display &quot;inline-block&quot;) that had auto width and height. Instead it is sufficient
+            to remove all these inline styles and create a RenderBlockFlow renderer for this &lt;div&gt; so that it
+            renders as a block, non-replaced element to achieve the intended illusion that the &lt;embed&gt; is a
+            single element.
+
+            * html/shadow/YouTubeEmbedShadowElement.cpp: Remove unused header HTMLEmbedElement.h and include
+            header RenderBlockFlow.h. Also update copyright in license block.
+            (WebCore::YouTubeEmbedShadowElement::YouTubeEmbedShadowElement): Remove inline styles as these
+            never worked as intended.
+            (WebCore::YouTubeEmbedShadowElement::createElementRenderer): Override; create a block-flow
+            renderer for us so that we layout as a block, non-replaced element.
+            * html/shadow/YouTubeEmbedShadowElement.h:
