Temporary window size reduction resets pinned state
Summary
Reducing the window size causes the menu to remove the pinned state and enter a 'always closed only' state which serves as an improved UX for devices with small screens. Unfortunately this also resets the pinned state session cookie instead of just deactivating it. This means temporarily reducing the window size completely resets any pinning session preferences.
Steps to reproduce
Open cookie debugger of choice. Monitor the pinned state session cookie as you set it and reduce the screen size.
Expected behavior
I expect the pinned state to simply deactivate on small screens rather than resetting so when I return to a larger window size, it returns to the specified preference.
