Prerequisites

• This is NOT a YouTube, Facebook, Twitch or a shortener/hosting site report. These sites MUST be reported by clicking their respective links.
• I read and understand the policy about what is a valid filter issue.
• I verified that this issue is not a duplicate. (Search here to find out.)
• I did not remove any of the default filter lists, or I have verified that the issue was not caused by removing any of the default lists.
• I did not enable additional filter lists, or I have verified that the issue still occurs without enabling additional filter lists.
• I do not have custom filters/rules, or I have verified that the issue still occurs without custom filters/rules.
• I am not using uBlock Origin along with other content blockers.
• I have verified that the web browser's built-in content blocker/tracking protection, network wide/DNS blocking, or my VPN is not causing the issue.
• I have verified that other extensions are not causing the issue.
• If this is about a breakage or detection, I have verified that it is caused by uBlock Origin and isn't a site issue.
• I did not answer truthfully to ALL the above checkboxes.

URL(s) where the issue occurs.

https://code.world/

Description

The site will fail to finish loading. The problem comes from this filter:

uAssets/filters/filters.txt

Line 9682 in 700c4b1

||wurfl.io/wurfl.js$script,3p

Which means WURFL never gets defined. Then https://code.world/js/codeworld.js (in strict mode) does this:

  window.codeworldEditor = CodeMirror.fromTextArea(editor, {
    /* ... */
    styleActiveLine: !WURFL || !WURFL.is_mobile,

Which results in Uncaught (in promise) ReferenceError: WURFL is not defined, and then nothing will work from there on: the code editor won't load (leaving just a tiny textarea), and the Run button will log Uncaught TypeError: window.codeworldEditor is undefined and not work.

Other extensions used

None.

I also opened google/codeworld#1644 to fix this on their end, but since that project hasn't had any commits in 18 months, I don't expect it to get merged any time soon.
