           Summary: navigator.appVersion returns version with comma i.e.,
                    15.6,2 instead of 15.6.2 in iOS 15.7
           Product: WebKit
           Version: Safari 15
          Hardware: iPhone / iPad
                OS: iOS 15
            Status: NEW
          Severity: Normal
          Priority: P2

Hello!

Our team has observed that in the recent update of iOS, i.e., iOS 15.7, when trying to access the browser version through navigator API i.e,

const appVersion = navigator.appVersion

useragent string returned contains a comma in its version. The above code snippet returns the following string

"5.0 (iPhone; CPU iPhone OS 15_7 like Mac OS X) AppleWebKit/605.1.15 (KHTML, like Gecko) Version/15.6,2 Mobile/15E148 Safari/604.1"

As can be observed, 15.6,2 has a comma in it instead of a dot. Is this an expected output of navigator.appVersion ? 


We have tested the same code snippet in the older version, and we got the version as 15.6.1. And there has been same cases in iPadOS 15.7
For reference: https://github.com/faisalman/ua-parser-js/issues/594

Let me know if there are any details required.

Thanks in advance
