QWebEngine gets stuck on a certain type of page

[kenchan]

Hello, I have a simple browser built using QWebEngineView.
When using it on Windows 10 it gets stuck at a certain kind of page, this one in particular. The same thing happens with the "simple browser" Qt example. It works fine on the macOS version.

Does any one know what is causing this and how to make it work with this of page?

Windows:
Qt 5.9.2 msvc 2015.

My thanks to anyone who can offer advice.

Just incase anyone is interested.
I could fix this by using a newer version of Qt (5.12.1) on windows.
