This is the first time I've seen this issue, I'm going to investigate why this is happening, so thank you for providing all this information. Once I know more I'll get back to you.
In that case, I'm not really sure what the issue is here, so I've reported it as a bug to our team and hopefully, they'll find time to explore this. If/when they do find time they'll update you here.
Thanks.
Phil
