Comment on attachment 206477 [details] Patch View in context: https://bugs.webkit.org/attachment.cgi?id=206477&action=review > Source/WebCore/html/HTMLPlugInImageElement.cpp:387 > + argList.append(JSC::jsBoolean(!m_snapshotImage)); I think we should put a comment here to explain that this parameter determines if the overlay should be always visible, which we want when we don't have a good snapshot.
