I've been having issues with animation as well, while using it in an {#each ...} block the item indexes keep getting mixed up, everything seems fine in my console logs no issues there just when using each and lodash's sortBy function to sort my array in turn animating the movement of the sorted list.

Can confirm, I wrote some minified code that used flip animations and tested it with both svelte 4 and svelte 5. Animation works fine in 4 and doesn't work in 5.

NICE! Look forward to getting back into animations!
