[Florian Müllner <fmuellner src gnome org>]

commit 55f02e9967abce59ba068b8fb4044929059e55aa

    dateMenu: Block notification banners while the calendar is open
    
    The new banner position interferes with the calendar drop-down. Resolve
    this by blocking banners while the calendar is shown.
