FSE Classic Block Issue

Severity: normal Version: 5.9
Component: General Keywords: reporter-feedback
Focuses: ui Cc:


I was checking FSE and available blocks! Trying to check Classic Block and got an error

TypeError: Cannot read properties of undefined (reading 'tinymce')

Maybe Tinymce is not working somehow or needs to enqueue properly!
