Hi @AritraDey-Dev. Thanks for your PR.

I'm waiting for a istio member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes-sigs/prow repository.

It's been a few years since I raised the request. Does this actually make sense?

Pros of CDN: loads quicker in parallel?
Cons: external dependency, versions can change upstream and break site (unless we pin them?)

[AritraDey-Dev]

Yes, definitely makes sense. The concern you mentioned—external changes breaking the site—is actually what's causing issues when the scripts are loaded from the static folder. That’s why I’ve marked this PR as a draft for now. There are a few UI breaking changes I’m still working through.

Do you recommend I continue refining the PR and eventually open it for review?
