QtWebEngine problem allow camera Qt5.6

[Cleiton Bueno]

Because in QtWebEngine 5.6 the onFeaturePermissionRequested does not work anymore? I can not release microphone and camera using this slot.
I tested on ARM Cortex-A9 as Desktop.

In my case this function works:

onFeaturePermissionRequested:
{
    console.log("onFeaturePermissionRequested");
    webEngineView.grantFeaturePermission(securityOrigin, feature, true);
}

Tested on Qt 5.6 and Qt 5.7 on Desktop and Embedded
