[Blazor] Cannot read/write properties on JSObjectReference

[mrpmorris]

Given the following JavaScript

export function createAudio(src) {
	return new Audio(src);
}

I can load it in, create an Audio instance, and start it playing like this

@page "/"
@inject IJSRuntime JSRuntime;

<button @onclick=@Play>Play</button>

	JSObjectReference AudioLib;
	JSObjectReference Audio;

	protected override async Task OnInitializedAsync()
	{
		await base.OnInitializedAsync();
		AudioLib = await JSRuntime.InvokeAsync<JSObjectReference>("import", "/Audio.js");
		Audio = await AudioLib.InvokeAsync<JSObjectReference>("createAudio", "/ElementsSong.ogg");
	}

	protected void Play()
	{
		_ = Audio.InvokeVoidAsync("play");
	}

However, I cannot get the currentTime of the Audio like this

CurrentTime = await Audio.InvokeAsync<decimal>("currentTime");

Instead I have to do something like this to convert the p

export function createAudio(src) {
	let result = new Audio(src);
	result.getCurrentTime = () => result.currentTime;
	return result;
}
