@Sriparno08 Thanks for submitting a PR! Per this comment, the comma is still necessary for certain versions of documentation and needs to be versioned for those instances. Can you update the PR to include the necessary versioning? You can find out more about our Liquid helpers for versioning here.

Updated it, @cmwilson21!
