Once:false about sal HOT 5 OPEN

I did a test and it looks like there is a problem with translation itself. Basically, when element is shifted by 20% of it's size, threshold (with value 0.5) doesn't match the center point of the element. Solution here is to either animate only when the animation has ended or apply new threshold for shifted elements. I will think about a fix for this problem.

Thanks for catching this bug! It looks like wrong threshold setting and I need to confirm it. I'll be back with patch as soon as possible.

After trying out some fixes it seems you have to offset the threshold by 20% to make up for the translateY, not 100% working yet though.

@mciastek any updates on how to solve this?

I checked this bug and I need to find a way how to resolve it without adding too much complexity to sal.js. To fix this I would need to let sal know how certain element was translated and update the threshold accordingly.

Here's a workaround for this problem. As Intersection Observer detects if specific amount of pixels are present in viewport, every time you translate the element, it's pixels are also translated. So to bypass this behaviour you need to wrap this element in a wrapper, which will be detected by sal. Next you need to disable animations on the wrapper. Then you can apply animation to proper element. Here's a simple demo - https://codesandbox.io/s/nkolnk00n0.

I will try to come up with solution, but I'm open to any ideas.
