Aggregation of klaro may cause issues depending on markup of page

Thank you for reporting this, i debugged this a bit and came to the conclusion that the klaro library expects to be loaded in a single js file, orherwise (bundled with other scripts using drupal aggregation) it will struggle to determine the currentscript the library was loaded with.
This needs to be fixed upstream, i created a new issue for this as the mentioned issue only applies to IE11, I can reproduce the error in any browser i tested though.

Until then i guess it makes sense to use the workaround to disable preprocessing

Merged and released with 3.0.0-rc6
