[I] GUI loader.js doesn't load with CSP in place [airflow]
LipuFei opened a new issue, #66589:
URL: https://github.com/apache/airflow/issues/66589
### Under which category would you file this issue?
Airflow Core
### Apache Airflow version
3.2.1
### What happened and how to reproduce it?
On the DAG execution details page, the "Details" block is stuck in "Loading". The content is actually available. I can click on the "copy" button to get the details.
Based on my browser's console output, I think it's CSP issue with the Javascript `loader.js`. I have a CSP policy `"script-src" 'self' 'unself-inline'", which blocks cross-site script loading. This pages tries to load `loader.js` from https://cdn.jsdelivr.net. I think this is why the UI is stuck in "Loading".
I'm not a Javascript expert, but I guess the fix is to bundle the relevant JS files so it doesn't need to go cross-site?
Here is a screenshot:

### What you think should happen instead?
The UI elements should load correctly with CSP in place.

Hi @LipuFei
Thanks for the report.
I'll take a look. It may be related on #66020

@LipuFei
This looks similar to #66020 and should be resolved by #66647, as it bundles Monaco instead of loading it from the CDN.

I can confirm that this is fixed in Airflow 3.2.2
