1. New Blazor web site
2. Any .razor page/component
3. Add @code {} block
4. Type in

@code {
    override OnA
}

5. Try to complete OnAfterRender (any other method as well, not specific to OnAfterRender)

RESULT:
Nothing gets inserted

EXPECTED:
Method skeleton inserted, similar to

protected override void OnAfterRender(bool firstRender)
{
    base.OnAfterRender(firstRender);
}
