What is the current behavior?

Issue Number: #31641
The case like this will print wrong current zone.

const zone = Zone.current;
const zoneA = zone.fork({
  name: 'A',
  onInvoke: function(
    parentDelegate, currentZone, targetZone, callback, applyThis, applyArgs, source) {
    expect(currentZone.name).toEqual('A');
    return parentDelegate.invoke(targetZone, callback, applyThis, applyArgs, source);
  }
});
const zoneB = zoneA.fork({
  name: 'B'
});
const zoneC = zoneB.fork({name: 'C'});
zoneC.run(function() {});

expect current zone to be A, but the result is B.

What is the new behavior?

the current zone will be A.
