custom_element_props_identifier after updating project

[opensas]

Describe the bug

In Input.svelte (for example) I get the following error:

	let {
		ref = $bindable(null),
		value = $bindable(),
		allowedChars,
		onkeydown: _onkeydown, // allow caller to set its own handler
		onbeforeinput: _onbeforeinput,
		oninput: _oninput,
		...restProps // ==>> Error custom_element_props_identifier
	}: Props = $props();

error: https://svelte.dev/docs/svelte/compiler-warnings#custom_element_props_identifier

/home/sas/devel/apps/dgiit/proyectos/encuestas/Main/Source/src/lib/components/input/Input.svelte
  18:3  error  Using a rest element or a non-destructured declaration with `$props()` means that Svelte can't infer what properties to expose when creating a custom element. Consider destructuring all the props or explicitly specifying the `customElement.props` option.

these are my dependencies:

Severity

annoyance

[opensas]

did a bit of research, it seems the problem happens when updating "svelte": "^5.25.6", to "svelte": "^5.33.10"

[ieedan]

I'm having trouble reproducing this myself do you think you could provide a reproduction?

I think I found the culprit: sveltejs/svelte#16003
