	@brief The JumpToElementDialog class
	A lightweight, transient "quick open" popup: type part of an element's
	label or other information to live-filter the elements on a diagram,
	then Enter to select the chosen element on the diagram and scroll it
	into view. Up/Down move through the filtered list, Escape cancels
	without changing the current selection.
