Investigate assorted log messages

[tallforasmurf]

The following messages appear on the console (regardless of the Qt log override):

A Parser-blocking, cross-origin script, http://ads.thehiveworks.com/delivery/spc.php?zones=245%7C246%7C387&source=&r=54663846&charset=UTF-8&loc=http%3A//sssscomic.com/comic.php, is invoked via document.write. This may be blocked by the browser if the device has poor network connectivity. See https://www.chromestatus.com/feature/5718547946799104 for more details.

and many more similar. Meanwhile, within the log file written by Cobro we have a similar number of

WARNING:root:Qt context: file http://ads.thehiveworks.com/delivery/spcjs.php?id=88 function ? line 9

and a lot of

and some of

ERROR:root:Qt context: file http://ads.thehiveworks.com/delivery/spcjs.php?id=88 function ? line 0
ERROR:root:Qt message: Refused to execute script from 'https://att.demdex.net/event?d_event=imp&d_src=127123&d_creative=92245680&d_placement=203711305&d_campaign=20141172&d_site=2932773&d_cb=169371072' because its MIME type ('image/gif') is not executable.

The following might be significant, does this mean a property of QWebEngine could be set?

ERROR:root:Qt context: file http://ads.thehiveworks.com/delivery/spcjs.php?id=88 function ? line 67
ERROR:root:Qt message: Failed to set referrer policy: The value '' is not one of 'always', 'default', 'never', 'origin-when-crossorigin', 'no-referrer', 'no-referrer-when-downgrade', 'origin', 'origin-when-cross-origin', or 'unsafe-url'. The referrer policy has been left unchanged.

first message occurs because of code in the loaded page. It and other messages perhaps can be filtered via: http://doc.qt.io/qt-5/qtwebengine-debugging.html#console-logging http://doc.qt.io/qt-5/qml-qtwebengine-webengineview.html#javaScriptConsoleMessage-signal

if the messages are originating in javascript, consider disabling it,
