draggable: false yet attempting to drag stops autoPlay

I have a photo carousel, I want it to be purely decorative so I set `draggable: false` however when i try to drag it, the autoplay stops.

```js
var flky2 = new Flickity( '.photos', {
accessibility: false,
adaptiveHeight: false,
imagesLoaded: true,
autoPlay: 3000,
cellAlign: 'center',
cellSelector:'.photo',
draggable: false,
freeScroll: false,
groupCells: false,
initialIndex: 0,
pauseAutoPlayOnHover: false,
percentPosition: true,
prevNextButtons: false,
pageDots: false,
resize: true,
wrapAround: true,
lazyLoad: true
});
```

Start by reproducing the issue with the provided Flickity configuration, focusing on the interaction between draggable handling and autoplay. Trace the drag-start path and autoplay pause logic, then verify that attempting to drag while draggable is false does not stop autoplay.
