Steps to reproduce (tested on iPhone XS, iOS 14): 1. Visit https://supermario3dallstars.nintendo.com/ 2. Keep zooming-in. Safari eventually crashes, the screen turns black with a spinner, and then the lockscreen appears. Debugging with Xcode doesn't produce a useful crash stack, since the app terminates with "Terminated due to memory issue".

The fix for this issue was needed outside the WebKit project, therefore this is being resolved as 'Moved'.
