ioS/safari Web app in standalone mode hangs while getting location

In iOS 14+, if I go to settings -> privateness -> location offerings -> safari web sites and set permit region get right of entry to to 'ask subsequent time or when I share', after which launch a website that I have introduced to the house display, if the website online's occur is set to display: standalone (a PWA), when I attempt to get the modern-day area, the modal to invite if chrome can ask for permission to get region is never proven and the app simply hangs out ready. If I open the same web page in normal safari, the popup is shown as predicted. Is this behavior anticipated or is it a malicious program in iOS/Safari?
