Mobile Safari doesn't always hide previously selected cells

[luksak]

Test case: https://codepen.io/luksak/pen/QPXoxr

While working on my current project I encountered a bug on Mobile Safari. When switching through slides, in some cases previously selected slides are still visible. To reproduce this, I have to move through the slider for quite some time. I couldn't find a pattern when this happens until now.

I have two findings regarding that might be relevant:

• I encountered cases where every single slide becomes visible for a short time when selecting slides using the Flickity.select() method.
• In Firefox I get those warnings during transitions: Error in parsing value for ‘opacity’. Declaration dropped. While debugging, sometimes alpha is of type Infinity inside Slide.setOpacity(). I'm not sure if this could be causing this and if it is relevant...

Thanks for reporting this issue. I'll have to take a look.
