Expected: City1____ and City1____. Got: City1____ and undefined. Why when strict mode is enabled eval("images.city1") is evaluated by QML JS engine into undefined? Plain javascript object are evaluated OK (not into undefined).

global.js

.pragma library

var global = {
  foo: null,
  repaint: null,
  p: { name: "Vasya" }
};

log

qml: eval('images.city1') =  City1____
qml: eval('images.city1') =  undefined

ocaml.js

"use strict";

Global.global.repaint = function(_a_) {
       //console.log("OCaml repaint");
       //console.log("eval('images') = ", eval("images") );
       //console.log("eval('images').city1 = ", eval("images").city1 );
       console.log("eval('images.city1') = ", eval("images.city1") );

       //console.log("eval('Global.global.p') = ", eval("Global.global.p") );
       //console.log("eval('Global.global.p').name = ", eval('Global.global.p').name );
       //console.log("eval('Global.global.p.name') = ", eval('Global.global.p.name') );

};
