Slider-layout => slideTransition props are not working

Hi,

I’ve implemented a simple slider-layout and I’m trying to configure the slideTransition to achieve a smooth transition between slides, but my code seems to have no effect on it.

my code below:

"slider-layout#brands": {
    "children": [
      "image#brand1",
      "image#brand2",
      "image#brand3"
    ],
    "props": {
      "infinite": true,
      "showNavigationArrows": "always",
      "showPaginationDots": "desktopOnly",
      "slideTransition": {
        "speed": 1500,
        "delay": 0,
        "timing": "ease-in"
      },
      "itemsPerPage": {
        "desktop": 5,
        "tablet": 3,
        "phone": 2
      },
      "autoplay": {
        "timeout": 5000
      }
    }
  }
(...)

am I missing something here?
