Description

In a library, I've a generic record that inherits from another generic record https://github.com/unoplatform/uno.extensions/blob/450d19f8fd9d4c53f327e5ecddbeeb50f86b020f/src/Uno.Extensions.Reactive/Operators/FeedToListFeedAdapter.cs#L14, but as soon as I try to use an instance of that record in a Dictionary my app is crashing.

Reproduction Steps

Unfortunately I was not able to create a repro for that issue. But here are the working (with an explicit GetHashCode) and failing version of my app on iOS.
working-Commerce.iOS.app.zip
crashing-Commerce.iOS.app.zip
.

Expected behavior

No crash :)

Actual behavior

Using mono for Android and iOS the app is crashing while using the same library is working fine on UWP / WinUI. Didn't test WebAssembly.

On Android I get a SIGABRT

[libc] Fatal signal 6 (SIGABRT), code -1 (SI_QUEUE) in tid 5768 (mmerce.Commerce), pid 5768 (mmerce.Commerce)

On iOS I get that stack trace:

Known Workarounds

I've implemented my own GetHashCode https://github.com/unoplatform/uno.extensions/blob/450d19f8fd9d4c53f327e5ecddbeeb50f86b020f/src/Uno.Extensions.Reactive/Operators/FeedToListFeedAdapter.cs#L96
