Object.entries sometimes passes an incorrect value to callback function

Reported by grygabri...@gmail.com, Mar 13 2018 
UserAgent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_12_6) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/65.0.3325.146 Safari/537.36

Steps to reproduce the problem:
1.  Use Chrome 65
2. Use Object.entries on a variety of objects (unclear what the criteria are to trigger this bug)
3. Observe that sometimes the second item in the array passed to the callback function will be a string instead of the actual value from the object. 

What is the expected behavior?
Object.entries should always pass a key and the correct corresponding value to the callback function. 

What went wrong?
Updated to Chrome 65, and suddenly my app that makes liberal use of Object.entries is broken. Debugging led me to discover that some objects will produce this problem, others will not. It is not clear what triggers this bug. Forcing use of the MDN polyfill fixes the issue. https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/entries#Polyfill

Did this work before? Yes 64

Sounds like a duplicate of  issue 804159 , which is fixed already so the fix will be delivered in the next update of 65.

Meanwhile you can use Chrome Canary, which is installed separately.

Sorry for the dupe! Apparently I suck at searching.

This bugtracker doesn't show fixed bugs by default unless you explicitly switch the search scope.

As per comment#1 and comment#3 this seems to be a duplicate of  issue 804159 . Hence merging into and removing Needs-Bisect label.

Please feel free to change if it is not same.

Thanks!
