Sorry folks, but I have to ask somewhere, and here seems as good a place as any because I don't know _who_ or _what_ is causing the problem.
For a long time I have had problems when I re-deploy some machine after editing their flow.
Opening the `performance` tab I see this:
Ok, I'll byte (😉) _Who_ is that?
It seems to be under the `Node-Red` scope.

i think it's a proxy URL created by/for the ACE editor worker thread. Nothing to be concerned about.
I've seen the same thing in the Monaco editor.
ACE is the code editor you see in the function node.
