TYPO3 Core

In TYPO3 7.6 it was possible to add menu items to the the top of the click menu
for instance in the List-Module.

We have a use-case with at custom table - where it should be possible to show a preview of the Item as well as
normal Record operations like edit etc. In current version of TYPO3 8 this is not possible AFAIK.
The location of menu items is handled via the getPriority method in the ProviderInterface in TYPO3 8.

Unfortunately the current implementation of the method addItems in RecordProvider class
prohibits entries above the priority in RecordProvider (60) which is what we want - due to the following code:

public function addItems(array $items): array
    {
        if (!empty($items)) {
            return $items;
        }
        $this->initialize();
        return $this->prepareItems($this->itemsConfiguration);
    }

Which means defining items with at priority above 60 will result in only these items being displayed
and NOT additionally items with a priority below 60.
