Steps to reproduce

1. Install Ibexa DXP v4.5
2. Create two tags
3. Create content type with ibexa_taxonomy_entry_assignment field and set taxonomy to tags
4. Create content from the content type you created
5. Select two tags and immediately remove it via 'x'
6. Publish

Result

The content still has removed tags

Expected

Removed tags should be not stored in the field

Note

if we edit the content and remove the tags and publish the changes, the tags are properly removed.

if we select new tags during editing, it will not be possible to delete them with 'x'. Deleting works if you press "select tags" and uncheck the tags in the popup, then the savings will be done correctly
