I just confirmed with Apple that the bug is fixed in iOS 13.4 beta 1 and updated Open Radar as Fixed: http://openradar.appspot.com/radar?id=4974489829900288

iOS Simulator Version 11.4 (921.4)
SimulatorKit 581.7
CoreSimulator 704.8

Xcode Version 11.4 beta (11N111s)

And this issue is no longer reproducible for me on iOS 13.4 beta 1. Thank you
