Animate example broken by #3046

[Conduitry]

Compare: https://svelte.dev/repl/animate?version=3.5.1 and https://svelte.dev/repl/animate?version=3.5.2

I'm getting some weird behavior when clicking around - stuff flying in from the upper left. If I revert just #3046 and run the example with my local version of Svelte, the issues seem to go away.
