TYPO3 Core

Deleting a section in flex currently does:

• add a t3js-flex-section-deleted to the section div
• the fields itself are kept and are probably (?) transmitted to dataHandler

This leads to funny fixes like https://review.typo3.org/#/c/44732/1 where validation did validate the "deleted" fields ...

This is also ugly: dataHandler still receives all field data, but probably just skips processing after it found out that the section itself is deleted.

Why can't delete just a) set the hidden "i'm a deleted section" marker and b) delete the single field dom altogether?
