When ever Particular key has empty value in XFCC Header, It is parsing wrongly

[mohankvnr]

We have header XFCC something like this
dns=dnsvalue1;dns=dnsvalue2;URI=;DNS=dnsvalue3

But parsing is giving unexpected result

What happened:
DNS = {dnsvalue1,dnsvalue2}
URI = ;DNS=dnsvalue3

What you expected to happen:
DNS = {dnsvalue1,dnsvalue2,dnsvalue3}

How to reproduce it (as minimally and precisely as possible):
Just use this as xfcc header - dns=dnsvalue1;dns=dnsvalue2;URI=;DNS=dnsvalue3
and parse the function

Anything else we need to know?:

Environment:

• go-sdk version: v1.20220411.3
• go version (e.g go version): 1.19
• OS (e.g: cat /etc/os-release): Mac
• Others:
