Code check

• the current code contains still path magic stuff: https://github.com/neos/neos-ui/blob/9.0/packages/neos-ui/src/manifest.js#L273
• https://github.com/neos/neos-ui/blob/913afb4a0b25fff15c0ec69a0832da86da3f162f/packages/neos-ui/src/manifest.js does not contain parent node path logic
• neos/neos-ui@a5a51e3 re-adds it
• neos/neos-ui@a2de6ed is wrongly implemented // !!! BUGFIX: Speed up move actions to prevent timeouts neos-ui#2764 for Neos 9, as it is dependent on the path logic

neos/neos-ui#2178

neos/neos-ui#3731

Check old code

neos/neos-ui#2764 needs to be adjusted
