How to disable removeEmpty formatting of empty tags in django in CKEditor, for example, for div?

Question

Django

CKEditor removes empty tags. This line <div class="class"></div> is removed completely. But <div class="class">123</div>it doesn't touch.
Tried different ACF settings in config.js like "CKEDITOR.dtd.$removeEmpty['div'] = false;", "config.templates_replaceContent = false;" Restarting and deleting the cache didn't help.
Maybe there is some easy way to remove this deletion in django settings?
There is already
'removePlugins': 'stylesheetparser',
'allowedContent': True
'templates_replaceContent': False
But it doesn't help.
Thank you!
