Avoid exception and console error message when SKCanvasView is created and then immediately disposed in Blazor#3427
Conversation
… and then immediately disposed. In javascript methods, return earlier when element is not available in DOM, also remove the error message in same scenario. In Balazor, the elements are removed from DOM before calling Dispose() of the component. So after each async method, the DOM element may be removed due to navigate to other node. No simple way to detect if the missing element is because the component is disposed, or software logic error. Ref: dotnet/aspnetcore#45777

Description of Change
In JavaScript methods, return early when the target element is no longer present in the DOM, and remove the related error log for this scenario.
In Blazor, elements can be removed from the DOM before a component’s Dispose() method is invoked. This means that after any async call, the corresponding DOM element may already have been removed due to navigation. There’s no reliable way to distinguish whether a missing element is due to normal component disposal or an actual logic error. This change updates the code to simply stop execution when the element is absent and suppress error logging for this case.
