IsBrowser doesn't seem to work when page is published

Here we are! I have pulled the same builder page in to our public workspace and pointed it at our public api.

The console in the builder interface shows the log lines absolutely fine but the live page doesn’t show the log lines and also doesn’t attempt the fetch (can be seen in the network tab)
