novnc stopped working with HTTP authentication in Chromium

[khimaros]

I'm now receiving 401 authentication failures during module load in vnc_lite.html.

It seems like the likely root cause is: 14ecdc6

Does polyfill work with HTTP basic auth?

Changing the <script> tag to <script type="module" crossorigin="anonymous"> (adding the crossorigin attribute) fixes the issue for me. It's odd that this isn't the default, but there are a few places that confirm this is the intended behavior:

https://bugs.chromium.org/p/chromium/issues/detail?id=717525
https://jakearchibald.com/2017/es-modules-in-browsers/ (see the "No credentials" section)
whatwg/html#1888

Well, that seems to be not entirely intended and is apparently changing:

whatwg/html#2557
whatwg/fetch#585

However until this rolls out we probably need that workaround.

The polyfill uses XHR which has different behaviour, so it should work fine.

Fixed in bf82644. Thanks for reporting and debugging this.
