[TYPO3] RC3: problem with IFSUB condition in a menu

[Claudio]

Hi all,
I am testing RC3 in order to upgrade my 3.8.1 site.
I noticed a different behaviour in the new release in a menu
which incldces an IFSUB condition to differentiate the layout of 
the menu entries containing subpages. 
Everything works for pages which include "normal" subpages: they
are regularly matched by IFSUB and displayed accordingly.
However, I have a page which actually includes just some links to
internal pages ("shortcuts"). In this case, it looks like the 
IFSUB condition is not matched by RC3, while it was on 3.8.1. 
Therefore the entry is displayed as if it didn't have any subpages. 
Is it a bug? A feature? How can I obtain the entry to be recognized
correctly? 
Thanks in advance

Claudio
