Adding Razvan to confirm if this is not the same case as on the bug mentioned above.
Thank you!

Yes, the root cause of the issue is the same as the one in Bug 1512665. I've raised the priority of that bug and I will close this one as a duplicate.

The inconsistency with alt+tab, click inside the address is most likely related to analytics HTTP requests which confuse the Changes actor that the page itself is being navigated away from.

Thanks!
