Breaking: #96517 - HMENU.collapse Typoscript removed

See Issue #96517

Description

The collapse TypoScript property of HMENU is removed without substitution.

When set, active HMENU items previously linked to their parent page, which was primarily a use-case for GMENU_LAYERS, which was removed in TYPO3 6.0.

Impact

Setting this TypoScript option has no effect anymore.

Affected Installations

TYPO3 installations with HMENU definitions having this option set which is highly unlikely.

Migration

Use a custom user function or the PSR-14 FilterMenuItemsEvent to modify the menu items.
