Update from 6/3 when clicking 'save' wouldn't publish: We rebuilt our Docker images (now with 7.3.5) and we are now able to save updates. However, on one page (and one page only, so far) we get an error when clicking 'publish' on a 'full edit': any idea what might be causing this?

Seems like a CKEditor error on first sight, could you create a issue on GitHub?

Will do
