Draft: Wrap GlobalDrawer's SearchField in a PopupSearchField
Requires patch to PopupSearchField: libraries/kirigami-addons!176 (merged)
Draft because it disables "focused by default and on page switch" behavior due to how popup always opens when its searchField gains active focus.
Also QtQuick Overlay manages to break shortcut for searchField (Ctrl+F)
And also I currently don't see any "live suggestions" model in the source code that I could use in place of a dummy generated array.
