Blazor - OnAfterRenderAsync called again even previous is not finished

I run into problem with multiple times called OnAfterRenderAsync(bool firstRender) even when a previous run of the same method in the same component is not yet finished.

protected override async Task OnAfterRenderAsync(bool firstRender){    if (firstRender)    {        _jsModule = await JsRuntime.LoadJSModule(this);        await _jsModule!.InvokeVoidAsync("doLogic");    }    await _jsModule!.InvokeVoidAsync("doSomethingElse");}

What the problem is:

1. On OnAfterRenderAsync runs first time with parameter firstRender = true
2. It goes inside first condition
3. I run StateHasChanged in parent component
4. On AfterRenderAsync is called second time with parameter firstRender = false, even first run is still running and it's inside first condition
5. Second run skipped first condition and goes directly to logic after, but _jsModule is still null here. So it fails

How this situation should be handled correctly? I tried use Semaphore, and then it works fine. But I think that this situation should be handled somehow by Blazor itself?

I found this problem with one component till now, because I run StateHasChanged in very short period of time.

I can imagine that it can happens also in other components and should be solved generally. Do you have some ideas or do I miss something?
