QQuickWidget (QtWebEngine) based applications crash in graphics device lost situations

QtWebEngine application crashes frequently on windows 10 with access violation in what looks like a 3rd party driver. Crashe stack attched.

It looks like  ANGLE does not check for a “lost device” scenario, (https://docs.microsoft.com/en-us/windows/uwp/gaming/handling-device-lost-scenarios)

When handling of lost device is tested using dxcap -forcetdr on command prompt the application responds in one of 3 ways:

• Goes into an unrecoverable state in which all of the UI is pure white or pure black

• Shows a dialog that says “Failed to create OpenGL context for format QSurfaceFormat(…)” and then crashes.
• The application immediately crashes (stack is in attachment forcetdr-crash.txt)

When a simple pyside2 app is tested with dxcap it immediately crashes.
