iOS 12 WebKit Crash

Hi Guys,

today I found a crash on xCode for only ios 12(12.4.8 (16G201) on iPad mini 2 (Model A1489)) for this

WebKit: WebKit::WebPageProxy::deviceScaleFactor() const + 0

So I attach the stack on main-thread to understand better the issue.

Code Block swift
#0 (null) in WebKit::WebPageProxy::deviceScaleFactor() const ()
#1 (null) in -[WKWebView _scrollViewIsRubberBanding] ()
#2 (null) in -[WKWebView _scrollViewIsInStableState:] ()
#3 (null) in -[WKWebView _scheduleVisibleContentRectUpdateAfterScrollInView:] ()
#4 (null) in -[WKWebView scrollViewDidScroll:] ()
#5 (null) in -[UIScrollView(UIScrollViewInternal) _notifyDidScroll] ()
#6 (null) in -[UIScrollView setContentOffset:] ()
#7 (null) in _UIScrollViewAdjustForOverlayInsetsChangeIfNecessary ()
#8 (null) in -[UIScrollView(UIScrollViewInternal) setSafeAreaInsets:] ()
#9 (null) in -[UIView _updateCombinedInsetsIfNecessary] ()
#10 (null) in -[UIView(Internal) _addSubview:positioned:relativeTo:] ()
#11 (null) in -[WKWebView _initializeWithConfiguration:] ()
#12 (null) in -[WKWebView initWithFrame:configuration:] ()
#13 0x0000000100ef6b8c in closure #1 in DMLWebViewController.webView.getter ()
#14 0x0000000100ef3ed4 in DMLWebViewController.webView.getter ()
#15 0x0000000100ef5564 in DMLWebViewController.loadView() ()
#16 0x0000000100ef5564 in @objc DMLWebViewController.loadView() ()
#17 (null) in -[UIViewController loadViewIfRequired] ()
#18 (null) in -[UIViewController view] ()


So Do you have any ideas?
