<div>
<pre>Running the iOS Mail app with a Debug build of WebKit, some of its web views used for message display are constantly failing the ASSERT(scale == [webView->_scrollView zoomScale]) in WKWebView.mm’s contentZoomScale(WKWebView *). In a typical example, one sees
(lldb) p scale
(CGFloat) $0 = 0.25
(lldb) p [(UIScrollView*)webView->_scrollView.m_ptr zoomScale]
(CGFloat) $1 = 1</pre>
