Manually initialized horizontal scroll not working

[dshook]

Hi there, first of all thanks for making this, seems like just what I need.

However, when I was getting it set up I ran into this issue that you can replicate in the Horizontal demo scene:

1. Turn off Self Initialize in the Recyclable Scroll Rect
2. Modify the Demo script awake function so it does the initialize with the datasource:

    private void Awake()
    {
        InitData();
        _recyclableScrollRect.Initialize(this);
    }

3. See that now the area wants to scroll vertically instead of horizontally.

I haven't been able to figure out what's causing this yet but I'll update this if I find out any more.

Bug occurred in RecyclableScrollRect.cs Start Function

protected override void Start()
{
       // remove
       vertical = true;
       horizontal = false;
       ///

        if (!Application.isPlaying) return;

        if (SelfInitialize) Initialize();
}

Remove vertical = true;, horizontal = false;
