Crash in RxScrollViewDelegateProxy when implementing custom UIScrollViewAccessibilityDelegate methods

[MartinColja]

I implemented my own UIScrollViewAccessibilityDelegate to handle translations, but I got a crash mentioning RxScrollViewDelegateProxy.
I mitigated this by making the conformance in the project myself, but I wanted to do it here as well.

I would also like to get some advice on how to write tests for this, because the crash only occurs when actually using voice over.
I tried to trigger it in code with scrollView.accessibilityScroll(.next) but issue doesn't happen and the delegate is ignored.

I think It can be done by creating a UI test, but I didn't find any existing ones for the Rx framework itself,
so I'm not sure if that would be the way to go.

You can check my implementation here 😄
