When visiting https://observablehq.com/d/e6a7da792f1db1a9 with Orion version 0.99.133.2.1-rc
we get CORS errors, when using safari the fetch request works as intended.
Disabling CORS restrictions makes d3.csv(...) work but introduces a visual bug (the GUI changes as if the user is not logged in.) Even in only logged in pages (included screenshots for the settings page, with safari's result being the expected on)
d3.csv(...) should not be returning CORS errors, the expected functionality would be the same as safari.
Fetch encountering CORS errors (Load error on Orion, no issues in safari):
