Temporary fixes
Each of the following measures fix the issue temporarily:
* Downgrading Elementor to 3.5.6
* Disabling the plugin Elementor Plus

I have yet to dig into the plugin code, but figured this might be something that’s of interest to the plugin authors in order to look into this and ideally publishing a patched version.

Thanks!
Mario
