TYPO3 Core

Steps to reproduce:

1. Create a custom content element with a file-reference-field (inline) inside a flexform
2. Create a record for the new content element and add an image in the flexform-field
3. Save
4. Delete the content element record

Expected behaviour:

• the sys_file_reference record pointing to the record is deleted (flagged as deleted), too

Actual behaviour:

• the sys_file_reference record still remains, also the reference is shown when listing the references of the file in fileadmin
