Carousel not working with svelte@5.28.3+ anymore

[frschi]

🐛 Bug report

The @zag-js/carousel component for Svelte appears to have a compatibility issue with Svelte versions 5.28.3 and newer. When using these Svelte versions, the carousel does not visually update when interacting with the next/prev buttons or indicators, even though the underlying state machine might be updating.

💥 Steps to reproduce

pnpm run dev the official zag/examples/svelte-ts project and check the carousel, there its broken too.
the svelte version in the svelte-ts project is set to "5.28.6", by setting it back to "5.28.2" or below the carousel works again.

🧐 Expected behavior

The carousel should slide to the next images

This was caused by this design decision in Svelte sveltejs/svelte#15895

Pushed a fix for this. We'll release a patch shortly.

thanks for the fast fix @segunadebayo <3, its working now however i just realize sveltejs/svelte#15895 also broke the collapsible. the data-part="content" doesnt disappear after closing. you can verify it as well in the zag/examples/svelte-ts project
