Array splice leads to infinite loop in each block

[PatrickG]

Describe the bug

This REPL comes from a help thread on discord.
Somehow the second cards.splice() (line 26) leads to an infinite loop in the {#each} block.

I could track it down to this while loop:

svelte/packages/svelte/src/internal/client/dom/blocks/each.js

Lines 708 to 712 in d92fa43

	while (node !== null && node !== end) {
	var next_node = /** @type {TemplateNode} */ (get_next_sibling(node));
	dest.before(node);
	node = next_node;
	}

I was not able to create a minimal reproduction of this issue.
Edit: It could mean the used libraray (@dnd-kit/dom/sortable) is messing with the dom, right?

Yea.. nvm, the lib messes with the dom.
