Have Blazor InputText keep focus after submitting - forms

Question

I'm building a little chat widget to my Blazor app. It works too, but to make it work more fluently, I'd like to make the focus stay in the InputText after submitting a message.
Any time I press enter, the message gets sent and received correctly. Unfortunately, the focus also goes wherever. This doesn't let you quickly type multiple messages into the chat.
I guess I could make a JS interop method sending the focus back to the InputText and call that after every submit, but I'd prefer to find a js-free solution.
My Razor markup is this:
<EditForm Model="message" OnSubmit="SendMessage">
<InputText type="text" #bind-Value="message.Message" />
</EditForm>
I send the message like this:
private async Task SendMessage()
{
Console.WriteLine("Send message " + message.Message);
var t = Service.SendMessage(message);
messages.Add(message);
message = new Library.Models.ChatMessage();
await t;
Console.WriteLine("Sending finished.");
}

This does not normally happen in an HTML form. The loss of focus is caused by the re-rendering of the tree.
As a workaround, not real pretty:
private async Task SendMessage()
{
Console.WriteLine("Send message " + message.Message);
var copy = new Library.Models.ChatMessage { Message = message.Message };
var t = Service.SendMessage(copy);
messages.Add(copy);
// message = new Library.Models.ChatMessage(); -- this was the problem
message.Message = "";
await t;
Console.WriteLine("Sending finished.");
}
I experimented a little with #key but I couldn't get that to work.
