🟡 Design — DotNetObjectReference created inside InitializeObserverAsync without being stored or disposed

In InitializeObserverAsync, a new DotNetObjectReference.Create(this) is passed to initObserver. This reference is not assigned to a field, so it cannot be disposed in DisposeAsync. The unmanaged JS side will hold a reference to the GC'd .NET object indefinitely, which is a memory leak.

The same pattern was correctly fixed for _selfReference (for the viewport observer). Apply the same treatment here — create a second _observerSelfReference field, assign it, and dispose it in DisposeAsync:

// At field level:
private DotNetObjectReference<ReaderCanvas>? _observerSelfReference;

// In InitializeObserverAsync:
_observerSelfReference = DotNetObjectReference.Create(this);
await module.InvokeVoidAsync("initObserver", _observerSelfReference, ...);

// In DisposeAsync:
_observerSelfReference?.Dispose();

🟡 Design — Still unresolved. Untracked DotNetObjectReference in InitializeObserverAsync.

DotNetObjectReference.Create(this) is called twice inside InitializeObserverAsync (once for initObserver and once already implicitly for initScrollListener via the _scrollListenerReference returned value). The reference passed to initObserver is not stored in a field and therefore cannot be disposed, creating a GC-root memory leak from the JS side.

Create a dedicated _observerSelfReference field:

// Field
private DotNetObjectReference<ReaderCanvas>? _observerSelfReference;

// In InitializeObserverAsync:
_observerSelfReference = DotNetObjectReference.Create(this);
await module.InvokeVoidAsync("initObserver", _observerSelfReference, ".reader-flow-container", ".block-wrapper");

// In DisposeAsync:
_observerSelfReference?.Dispose();
