[Bug] `jsonServerMain.js` throws error `Cookie “_cfuvid” has been rejected`

MR: Pending

Description

Noticed this error in the logs while working on the Web IDE in .com:

Cookie “_cfuvid” has been rejected because it is foreign and does not have the “Partitioned“ attribute.

Acceptance Criteria

• Investigate cause of issue.
• Resolve root cause so that error isn't thrown in the console.
