    ///
    /// [`Popover`][crate::Popover] has a main node with name `popover`, an arrow with name `arrow`,
    /// and another node for the content named `contents`. The `popover` node always
    /// gets the `.background` style class. It also gets the `.menu` style class
    /// if the popover is menu-like, e.g. is a [`PopoverMenu`][crate::PopoverMenu].
    ///
    /// Particular uses of [`Popover`][crate::Popover], such as touch selection popups or
    /// magnifiers in [`Entry`][crate::Entry] or [`TextView`][crate::TextView] get style classes like
    /// `.touch-selection` or `.magnifier` to differentiate from plain popovers.
    ///
    /// When styling a popover directly, the `popover` node should usually
    /// not have any background. The visible part of the popover can have
    /// a shadow. To specify it in CSS, set the box-shadow of the `contents` node.
    ///
    /// Note that, in order to accomplish appropriate arrow visuals, [`Popover`][crate::Popover]
    /// uses custom drawing for the `arrow` node. This makes it possible for the
    /// arrow to change its shape dynamically, but it also limits the possibilities
    /// of styling it using CSS. In particular, the `arrow` gets drawn over the
    /// `content` node's border and shadow, so they look like one shape, which
    /// means that the border width of the `content` node and the `arrow` node should
    /// be the same. The arrow also does not support any border shape other than
    /// solid, no border-radius, only one border width (border-bottom-width is
    /// used) and no box-shadow.
