SetFocus not working when called from Construct

According to this post:

UMG - NativeConstruct + SetUserFocus

Hello, SetUserFocus calls are ignored when trying to focus a Widget in NativeConstruct() in code (or OnConstruct in Blueprint). If you add any amount of delay to the call, the call will succeed, though this isn’t a good solution. Setting focus in NativeConstruct() is a common operation since that’s where screens initialize. One thing to note is that setting focus through setting the input mode always works, though this is also not a great solution since we might not always want to reset the inp…

Something like this would work:

void USlateUtils::SetFocusOrDelayedFocus(APlayerController* InPlayerController, UWidget* InWidget) {
	if (!IsValid(InPlayerController) || !IsValid(InWidget)) {
		return;
	}

	InWidget->SetUserFocus(InPlayerController);
	if (!InWidget->HasUserFocus(InPlayerController)) {
		FLocalPlayerContext Context(InPlayerController);
		if (ULocalPlayer* LocalPlayer = Context.GetLocalPlayer()) {
			TOptional<int32> UserIndex = FSlateApplication::Get().GetUserIndexForController(LocalPlayer->GetControllerId());
			if (UserIndex.IsSet()) {
				LocalPlayer->GetSlateOperations().SetUserFocus(InWidget->GetCachedWidget().ToSharedRef());
			}
		}
	}
}

That is bloody ugly and messes with the next frame. Something tells me we can’t we just enforce the “SafeWidget” creation at that point without messing up something else. Thoughts?
