Struct PopupNavSession 

pub struct PopupNavSession {
    pub open_signal: String,
    pub panel: Entity,
    pub prev_focus: Option<Entity>,
    pub prev_focus_visible: bool,
    pub needs_scroll: bool,
}

The one live popup keyboard session (dropdown or menu panel). At most one popup owns the keyboard at a time - nested menus are a later wave; today’s <menu> is a flat panel.

Fields

open_signal: String

Open-state signal the session is keyed on (__dropdown_open:* / __menu_open:*).

panel: Entity

The PopupPanel entity.

prev_focus: Option<Entity>

Focus holder at open time, restored when a menu closes. Dropdowns restore to their header instead (Qt returns focus to the combobox).

prev_focus_visible: bool

Whether the pre-open focus carried FocusVisible (keyboard focus) - the restored focus mirrors it.

needs_scroll: bool

Initial scroll-into-view still pending: the panel mounts lazily on first open, so the highlighted row has no measured Transform until a layout pass has run. Cleared once applied.
