ImPlot heavily relies on DragLineX call order but it shall not (IMO)

ImPlot heavily relies on DragLineX call order but it shall not (IMO)
Hello.
Let us change the void ShowDemo_DragLines() code the following way:
Old code:
`ImPlot::DragLineX(0,&x1,ImVec4(1,1,1,1),1,flags);
ImPlot::DragLineX(1,&x2,ImVec4(1,1,1,1),1,flags);

New code:
if (x1 < x2) {
ImPlot::DragLineX(0, &x1, ImVec4(1, 1, 1, 1), 1, flags);
ImPlot::DragLineX(1, &x2, ImVec4(1, 1, 1, 1), 1, flags);
}
else {
ImPlot::DragLineX(1, &x2, ImVec4(1, 1, 1, 1), 1, flags);
ImPlot::DragLineX(0, &x1, ImVec4(1, 1, 1, 1), 1, flags);
}`
And everything stops working if one dragging lineX goes over the another one.
In my very case the drag lines are sorted and I cannot afford to use static variable in a real-life application.
Please, inform me if it is the intentional behavior.
