Steps to reproduce the problem:
1. Open the Developer Tools on this page.
2. Enable breaking on uncaught/caught exceptions.
4. Enter in the console -
window.location.hash = "3333";
 setTimeout(() =>
 {
  window.history.back();
  window.nonexistentmethod();
 },
 1000);

What is the expected behavior?
The debugger breaks on window.nonexistentmethod();

What went wrong?
The debugger breaks on window.nonexistentmethod(); but immediately moves on (the programmatic navigation is committed).

Did this work before? N/A
