UIX hiding dashboard on new desktop

Hello,

When i add new UIX dashboard and use this:

myTab.ShowDashboard("my-dashboard", {});
myTab.Select();

And log in the vault using web portal, dashboard is showing by the default. So if i want to dismis this behaviour, i just comment the myTab.Select(); and everything is working fine.

But that not apply for new desktop ui, even when i comment the myTab.Select();, it still pop up the dashboard when i log in the vault.
