Is it working fine on other browsers ?

l446240525@ Thanks for the issue.

Unable to reproduce the issue on windows 7 using chrome version 50.0.2661.102.
Observed the output as 10 for both Chrome and Firefox.

Request you please try the issue by upgrading chrome to latest stable and if the issue still persists please provide us the expected output to triage the issue further.

Thanks,

Closing the above issue as Wontfix due to lack of user response. 

However, feel free to report a new issue if encountered with any other issue again with newer version of chrome.

Thank you!
