Crossfade transitions not smooth

[hanielu]

Describe the bug

Triggering a crossfade in quick succession causes the element being animated to instantly snap to their new position and not animate in.
This isn't the case with framer-motion's layout transitions, and wasn't the case in older versions of svelte (svelte 4)
