Describe the bug
Running svelte-check on <Textfield bind:value /> fails with the following error:

Property 'value' is incompatible with index signature.
   Type 'string' is not assignable to type '((false | Attachment<HTMLSpanElement>) & (false | Attachment<HTMLLabelElement>)) | null | undefined'. (ts)
	<Textfield bind:value={searchTerm} input$id={searchInputId} input$placeholder="Filter..." class="search-input">

To Reproduce
Steps to reproduce the behavior:

1. Create a new SvelteKit application
2. Use Textfield in a page (other components have this problem as well, such as TabBar) and pass value (also happens with required, disabled etc.)
3. Run npm run check and see the error.

CodeSandbox

Expected behavior
Using value on Textfield should not produce type errors.

Additional context
This seems to be caused by the new Attachments feature.
