.NET5 RC1 Blazor JS interop issue with HTML element return type.

I have an issue with JS interop. In the following scenario JS should return an HTML element which is stored as `ElementReference ` in Blazor. Later at some point in the code I would like to use the stored reference.
I know about the `@ref=""` usage but the problem is I have different components so cannot access the active element of the `document`.

**Here is the JS**
```
export function focusElement(element) { //This receives ElementReference from Blazor and works..
    if (element && typeof element.focus === "function") {
        element.focus();
    }
}

export function getFocusedElement() {
    return document.activeElement; //This should return HTML element as ElementReference to Blazor but fails...
}
```

**Blazor code which tries to store the `JSObjectReference`**

```
@inject IJSRuntime _jsRuntime;
...

JSObjectReference _focusJs = await _jsRuntime.InvokeAsync<JSObjectReference>("import", "./_content/<PACKAGE>/focus.js");
ElementReference _previousFocusedElement = await _focusJs.InvokeAsync<ElementReference>("getFocusedElement");
```

**And it fails various errors based on the active HTML element type**

**In case of a <button> element**
```
