[Stepping] Can't step over upper in call stack

[Loirooriol]

Run this code in the console:

function f() {
  var foo = 123;
  ++foo;
  return foo;
}
function g() {
  debugger;
  var bar = f();
  ++bar;
}
g();

1. The debugger pauses at debugger; in function g.
2. Step in. The debugger pauses at var bar = f(); in function g.
3. Step in. The debugger pauses at var foo = 123; in function f.
4. In call stack, click function g. The debugger goes back to var bar = f(); in function g.
5. Step over.

Result: The debugger pauses at ++foo; in function f.
Expected: The debugger pauses at ++bar; in function g.

@Loirooriol so just to be clear, you would expect a different behavior stepping behavior based on the selected frame in the call stack?

[Loirooriol]

Yes, I think it would be more useful. Not sure if it's what debuggers usually do, though.

[jasonLaster]

Yeah, its certainly something I've thought about as well. It seems like something we could do in the happy case.

One challenge would be if we hit a debugger statement or breakpoint while heading to the selected path, but that might be okay...

I'm moving this to the icebox. We will prioritize it in our next release scheduling meeting.
