UWP: "SSL handshake failed" even when ignoring ssl errors

When making a request with qnam and the following error occurs on UWP:

qt.winrtrunner.app: error (A certificate chain processed, but terminated in a root certificate which is not trusted by the trust provider.)

ignoring ssl errors doesn't seem to have an effect.The request fails either way with:

QNetworkReply::SslHandshakeFailedError

In contrast for example on Windows desktop the same problem does not occur.

Steps to reproduce the problem:

1. run the attached project on UWP (=> ssl handshake failed)
2. run the attached project for comparison on Windows desktop (=> no error)
