Standalone Debugging Issue after v8.43.0

Type of issue

Bug debugging when using standalone library after prebid 8.43.0

Description

The standalone version of debugging hosted on jsdeliver has changed considerable and the new one doesn't work and freezes the auction.
Check out (even if minimized, the files clearly are different):
https://cdn.jsdelivr.net/npm/prebid.js@8.42.0/dist/debugging-standalone.js
vs
https://cdn.jsdelivr.net/npm/prebid.js@8.43.0/dist/debugging-standalone.js

Probably is due the building process and the changes made in webpack.conf.js here: https://github.com/prebid/Prebid.js/pull/11269/files#diff-49d59f0d7ac5380eec649778a04447e20fd504be848b640e42a70ab2675dc7a1

Probably debugging-standalone needs an exception.

Steps to reproduce

To test that is not working: just used a simple debugging configuration on a prebid build that uses the standalone debugging intercept, like:
pbjs.que.push(function() { pbjs.setConfig({ debugging: { enabled: true, intercept: [ { when: {src: 'client'}, then: { cpm: 20 } } ] } }) });

Working with prebid version 8.42.0: https://jsfiddle.net/skruthmw/1/
Not working with prebid version 8.43.0: https://jsfiddle.net/skruthmw/0/
The prebid version is only relevant since it changes the jsdeliver URL location from where debugging-standalone.js is loaded.

Expected results

8.43.0 to work as on 8.42.0

Actual results

Not only that the interceptor doesn't work but the auction freezes and nothing happens. Some ads are still displayed due to GAM FAIL SAFE timeout.
