These scriptlets (one by one) helps on desktop when added /aas/r45d/vki/*$script,redirect=noopjs,badfilter.
On iOS that rules does not work at all. 'abort-on-property-read' does not work even after page loads.

I might be wrong, but I think that the problem may be the way how Object.defineProperty works in Safari.
There is a test page - https://jsfiddle.net/k0z6y4bq/

Code:

<script>
Object.defineProperty(window, 'foo', {get: function(){ return ()=>console.log('get'); }, set: function(){ console.log('set'); } });
</script>

<script>
function foo () { console.log('O.o'); };
</script>

<script>
foo();
</script>

In Safari, foo is overwritten by function foo () { console.log('O.o'); }; and in the console it shows O.o.
But in Chrome/Firefox, foo is not overwritten (there is an error like Uncaught SyntaxError: Identifier 'foo' has already been declared) and foo() returns get in the console.
