Store navigation HTTP requests do not honor the workspace selection cookie during the session. In fact, during a single session, a user can receive responses from all workspaces being tested.

1. Create an A/B test in your store using the VTEX IO CLI
2. Open the "Application" tab in Chrome DevTools (or equivalent in your browser)
   1. Navigate through the store and clear your VtexWorkspace cookie after every click
   2. You should see values change eventually, even though the session cookie did not change
3. Open the "Network" tab in Chrome DevTools (or equivalent in your browser)
   1. Navigate through the store and observe the HTTP requests that are made
   2. You should see that the workspace query string is set to different values throughout the session

There is no workaround available. A/B testing is not recommended and their results should not be considered correct until this Known Issue is fixed.
