@AlekseyTs this is hitting the new warning from dotnet/roslyn#71103 in this test:

runtime/src/tests/Loader/classloader/InlineArray/InlineArrayValid.cs

Lines 197 to 205 in c63c752

	[InlineArray(Length)]
	ref struct ObjShortArrRef
	{
	public const int Length = 100;
	public (object, short) element;
	[UnscopedRef]
	public ref (object o, short s) At(int i) => ref Unsafe.Add(ref element, i);
	}

Is that expected and should we suppress the warning in this case?

It looks like the scenario matches the one from the compiler unit-test, https://github.com/dotnet/roslyn/blob/main/src/Compilers/CSharp/Test/Emit2/Semantics/InlineArrayTests.cs#L2143. I'd say the same warning is expected.
