Hey I think this is what is causing my issue (https://github.com/itchio/itch.io/issues/1083) with flicksy (https://candle.itch.io/flicksy), which relies on being able to fetch its own javascript source code. I'm not trying to access it from outside of itch at all, but the javascript code seems to end up on a different origin to the page that's actually running it when you launch it from the itch page. Is there a way to disable this?
I tripped over this because my code assumed that the only script tags in the page were my own--I have an issue (https://github.com/itchio/itch.io/issues/1083) where I described how I'm working around this now, but it would be good to have a less hard-coded way to do this.
