Thanks for the PR! This looks good so far, but I think we also need to handle the {:else} transitioning out when elements are added to the {#each} again.

I was able to figure out how to add an outtro, but in the original issue #4970, the animation for the outtro, the list items get added above the 'No Item' div, wasn't sure how to get it to do that, wondering if anyone can point me in the right direction?

Current behavior with this PR is the item list gets added back below the 'No item' div.

Thanks.

This has been absorbed into #5179, which I just merged, and also gave you co-author credit while doing so. Thank you!
