[AC-3003] global `setTimeout()` short-circuits the target object

setTimeout seems to break method replacements by spies. The this in object a does not refer to the same c as replaced by the spy. Tried this on SDK 1.7.0, 1.8.2, and 2.0.1 with Sinon.js and Jasmine testing frameworks. {noformat} a = { b: function() { Ti.API.debug("a.b() called"); this.c(); }, c: function() { Ti.API.debug("a.c() called"); } }; describe("some test suite", function(){ it("some test case", function(){ setTimeout(function(){ a.b(); }, 1000); // or setTimeout(function(){ eval("a.b();"); }, 1000); spyOn(a, "b"); spyOn(a, "c"); // or sinon.spy(a, "b"); // sinon.spy(a, "c"); // After 1 second... // "[DEBUG] a.b() called" is printed to terminal // "[DEBUG] a.c() called" is printed to terminal expect(a.b.callCount).toEqual(0); // succeed expect(a.b).toHaveBeenCalled(); // fail expect(a.c.callCount).toEqual(0); // succeed expect(a.c).toHaveBeenCalled(); // fail }); }); {noformat}
