Disable Line-Break-Removal in Blazor Event

I am using Blazor with .Net 8. My goal is to be able to have multiline lambda function bodies.

Here is an example:

<Button
   Content="test123"
   OnClick=@(() => { if (ShowInitialConfigDialog) { _configPage++; } else { OnClose.InvokeAsync(config); } })
   />

If I add a line break somewhere inside the curly brackets in the OnClick lambda function, they are instantly removed by Rider. How can I disable this?

Thanks Mario
