--- Comment #2 from youenn fablet <youennf at gmail.com> ---
The issue does not seem to be related with CORS checks per se but more on how we keep/retriev that information around.

The main script element is inline so there is no CachedScript and 
The cachedScript passed to ScriptExecutionContext::sanitizeScriptError is the top-level script which is inline, so it is null.

We rely solely on the source URL, which is the one of the cross-origin subresource, hence the issue.
I am not sure of the best way to retrieve the related CachedScript here.
Or even if that should be done that way.

Any insight?
