Orion allows users to suspend whole windows and close them. When reopening the windows (by clicking on these grayed-out windows on the sidebar), the users gets a new window with the old tabs, but the first tab is always focused, as opposed to the tab that the user last opened.
It would be nice to focus on the last tab the user was focuing on when they suspended the window.
For example, Safari focuses on the last tab use user focused on in a tab group when they return to that tab group.
