Hello.
Could you test this on online.me, too? And please provide the steps to reproduce the problem.
I am waiting for the invitation from online.mr, but the comparison of my site and una.io can be seen in the video.

Even at online.me the header block behaves different then Una.io.
At Online.me page reloads also causes the header images to reload again and disappearing for a short time.
