fix: add missing handler

[Nightfallstorm]

Additionally, added a fix for CTD when deleting a WorldSpaceMenu, such as in QuicklootVR. The menu's menuNode is already deleted when the pointer is reset if it has no ref counts, leading to code that calls DeleteThis twice:

// Decompiled C code from QuickLoot DLL
if ( v3 )
    {
      (v3->DetachChild2)(v3);
      this->menuNode._ptr->DeleteThis(this->menuNode._ptr);
      v4 = this->menuNode._ptr;
      if ( v4 )
      {
        if ( _InterlockedExchangeAdd(&v4->_refCount, 0xFFFFFFFF) == 1 )
          v4->DeleteThis(v4);
        this->menuNode._ptr = 0i64;
      }
    }

Removed the explicit DeleteThis call to fix this.

Is the deleteme only a VR fix?

Yes it is, the WorldSpaceMenu only exists in VR
