How can I change the default behavior of console.log in Safari?

In Safari with no add-ons, console.log will show the object at the last state of execution, not at the state when console.log was called.

I have to clone the object just to output it via console.log to get the state of the object at that line.


var test = {a: true}
console.log(test); // {a: false}
test.a = false; 
console.log(test); // {a: false}
