[JENKINS-51221] Email-Ext groovy.template does show wrong changes

I use the groovy template from email-ext in a multibranch pipeline (blue ocean).

However, for unknown reason the email contains in the changed section hundreds of files, which where not touched in the commit (they are all from the 3rdpart directory in the src repo) but totally unrelated to any changes.
