Hi Kimmo,
I've hosted an html build of the test game here:
https://bug261685-test.netlify.app/

However, I did some testing with this, and its behavior is a bit different.
Also, keep in mind that when you load this website, the engine loading is stuck at 0% for around 2 minutes, but only for the initial load. I assume this is because it's preparing for loading the textures. 

So, when the actual test application has started, it will freeze early when loading when it's the first time loading it up (I'm talking about the second loading screen, not the first one with the grey letters). If you then reload the page, it will freeze later on while loading (for me it is 82.5, in percent). However, I could not get it past this first "test". 

In comparison, the mobile app usually finishes the test and you have to press the button to switch layouts and start loading again a few times to get it to crash or even restart the app a few times. Here with the website, I could not get it to not freeze. That's also a difference - the website freezes, the app restarts the webview. But I assume this is part of how webview's in xcode work. 
I'm trying this out on the 11 Pro and I can get it quite far (82.5%) so I assume you might get past it on devices with more ram, unless there is a limit in Safari.
