--- Comment #2 from David Dworken <ddworken at google.com> ---
I spoke too soon. I now can reproduce this non-flakily and can confirm that COOP is somehow tied to this. To reproduce non-flakily:

1. Close all other Safari tabs and wait a few seconds 
2. Start mitmproxy with the script:

```
def response(flow):
    if 'www.google.com' in flow.request.host and not b'cross-origin-opener-policy' in flow.response.headers:
        flow.response.headers["cross-origin-opener-policy"] = "same-origin"
```

3. Go to www.google.com 
4. Search for "a" and click on the first result (wikipedia) 
5. Press the back button 

Expected result: End up on the results page for the search query "a" 
Actual result: You'll consistently end up back on www.google.com thereby skipping over a history entry
