Describe the bug

Jellyfin web send duplicate requests with different URLs for the Item. Can be tested in unstable demo

Issue is on anything detail (Show, Movie Season episode) and not on library listing

URLs - Payload is identical

Tested a bit around, and it seems to be the polyfill import 'regenerator-runtime/runtime'; that cases the requests. Removed it in my lcoal version and one of those requests is gone.

The polyfill itself is archived for 1.5 years.
