TYPO3 Core

Setting a page type to "shortcut" with "shortcut_mode = 1" (first subpage) and the first subpage type is type "mountpoint" with "mount_pid_ol = 1" (show mounted page) and the mounted page is within a foreign site (domain), the link (menu processor, typolink) generated for the shortcut itself incorrectly points to the mountpoint target page within the foreign site. Instead when setting "shortcut_mode = 0" and explicitly assign the mountpoint page, links are correctly generated.

- site1.domain.tld
--- Shortcut (shortcut_mode = 1) ---> wrongly resolves to "https://site2.domain.tld/Page
------ Mountpoint (mount_pid_ol = 1, mount_pid = 123)

- site2.domain.tld
--- Page (uid: 123)
