Editor should not report Curl/web-request errors and pause playback

Frequently the editor is reporting “Curl error xx” or in extreme circumstances - “Curl Error 28: Failed to connect to xxx port 443: Timed out”.
Now this seems to be deep in the http/netwokring code but it should not spawn an error in the editor - it should just pass it back via the UnityWebRequest as a failure.
Why does it throw an editor error?

I don’t recall this ever happening when WWW was the way to do web calls so is it something introduced?

Unity 2019.4
