TYPO3 Core

The value of the target field is always returned as an empty string in the menus if the doktype is "Shortcut(4)".

I've created the following Menu:

page {
    10 {
        dataProcessing {
            30 = TYPO3\CMS\Frontend\DataProcessing\MenuProcessor
            30 {
                levels = 1
                as = testnavigation
                special = directory
                special.value = {$menus.metaNavigation}
            }
        }
    }
 }

This is also the case for menus created using HMENU objects.

EDIT:
This only happens if the "Shortcut" page and the "original" page are in different siteroots.
