Switching to Calendar View Automatically Replaces the Main Sidebar Navigation

Switching to the Upcoming calendar view automatically opens the calendar display settings in the sidebar, replacing the main navigation. This makes it inconvenient to quickly check the calendar and navigate elsewhere, as I first have to return to the main sidebar.

This happens when:

1. Switching from Upcoming list view to calendar view.

2. Opening Upcoming from another section when calendar view was previously selected.

The sidebar should stay on the main navigation. Calendar settings should only open when explicitly clicking the arrow next to Upcoming.

This already works correctly when manually returning to the main sidebar from the calendar settings and then clicking Upcoming again.
