QWebEngineLoadingInfo::errorDomain() returns WebEngineError::InternalErrorDomain when there is no error

The errorCode is used to provide the HTTP Status Code :

m_loadingInfo.errorCode = http_statuscode;

However, the error code is always used to find the error domain:

void WebContentsDelegateQt::emitLoadFinished(bool isErrorPage)
{
    ...
    auto errorDomain = static_cast<QWebEngineLoadingInfo::ErrorDomain>(WebEngineError::toQtErrorDomain(m_loadingInfo.errorCode));
     ...
}

And for some reason WebEngineError::toQtErrorDomain() returns WebEngineError::InternalErrorDomain when the error code does not fit in other domains, which is the case when there is no error and the errorCode is in fact an HTTP status code.

I suggest changing WebEngineError::toQtErrorDomain() so that a positive error code is included in WebEngineError::NoErrorDomain.
