Upgrading a plugin makes CDN cache unusable and has to be manually invalidated

Issue Summary

whenever there are plugin-related changes (like updating the plugin, enabling/disabling the plugin, install a new plugin) we see that the CDN cache is broken, and hence the page layout displayed on Jira UI is all distorted and broken.

After invalidating the cache on the CDN front, things are working fine again.

Steps to Reproduce

N/A

Expected Results

We don't refer to the old CDN cache. A new cache should be referred and the old one should be manually invalidated.

Actual Results

page layout displayed on Jira UI is all distorted and broken.
No exceptions in the logs.

Workaround

Manually invalidating the cache on the CDN front resolves the problem.
