you need to add range property for that to work :)

hmmm.....

but....

I see the warning issue (with the perf isuse, too)... the performance/lag is being caused by the thousands of console.warn() ... and those warnings are coming from Svelte 5.9.0 ... if you change it to 5.1.0 it is not causing any problems;

.... I don't know what Svelte have changed but it seems like it is ALMOST breaking change, and a little worrying to say the least.
