TYPO3 Core

When deleting all Items via the recycler icon and saving the parent record, all the items will come back after the reload of the form.

Deleting single or multiple items is working fine when there is at least one item left. But as soon as all items should be removed, it fails.

You could reproduce it very easy within the styleguide extension on page "flex", third tab "section container". See screenshot: https://docs.typo3.org/m/typo3/reference-tca/master/en-us/ColumnsConfig/Type/Flex.html
