We are currently using the iOS JS SDK version 8.10.0. We have tested this issue on iPhone 7 running iOS 13.3.1.
Thanks for any help!
I have been able to reproduce this issue on our side as well. Unfortunately, it seems to be part of the way WKWebView behaves at the moment. We will be considering a way to handle this particular situation in the future.
Sorry for the inconvenience, let us know if you have any more trouble.
