Cannot load an image or css file directly, invalid URL error is thrown

Related to #4761 in the exact same setup. This is a second issue.

I am attempting to load https://mysite/image/favicon.png so that I can browser.executeScript(() => { localStorage.setItem('token', 123456); }).

The reason for doing this is loading an app page will trigger an oauth redirect. Given that we support multiple oauth pages, this is not ideal. Therefore, loading a file from the same domain would allow us to put a previously retrieved token into localStorage before loading up an app page, avoiding the need to test all oauth flows.

This is not a complex setup. The error output is:

  - Failed: unknown error: unhandled inspector error: {"code":-32000,"message":"Cannot navigate to invalid URL"}
