Description

Multiple PHP warnings with PHP V8 appears when you look at the history and click on a "Rollback (preview)" button.

PHP Warning: Undefined array key "action" in typo3/sysext/backend/Classes/History/RecordHistory.php line 176
PHP Warning: Undefined array key "sys_file_reference:107" in typo3/sysext/backend/Classes/Controller/ContentElement/ElementHistoryController.php line 269
PHP Warning: Undefined array key "pages:41" in typo3/sysext/backend/Classes/Controller/ContentElement/ElementHistoryController.php line 269

Those warnings appears in history for pages as well as records in list view and page view.

This is because in PHP V8, a number of warnings have been converted into Error exceptions and especially : Attempting to read an undefined array key.
