-- `allowTransitions` ... Most svelte transitions (including the built-in ones) use inline styles. However, it is theoretically possible to only use transitions that don't (see this [issue](https://github.com/sveltejs/svelte/issues/6662) about removing inline styles from built-in transitions). This option allows transitions to be used in such cases. Default `false`.
+- `allowTransitions` ... Some svelte transitions (including the built-in ones in Svelte 4 and older) use inline styles. This option allows transitions to be used. Default `true`.
