[file] strict validation not compatible with react-dropzone

[csantos-nydig]

I'm mostly curious why this validation exists:

happy-dom/packages/happy-dom/src/nodes/html-input-element/HTMLInputElement.ts

Lines 795 to 802 in e6f9127

	case 'file':
	if (value !== '') {
	throw new DOMException(
	'Input elements of type "file" may only programmatically set the value to empty string.',
	DOMExceptionNameEnum.invalidStateError
	);
	}
	break;

And if it can be removed or updated?

Context

I'm using react-dropzone and they have this line https://github.com/react-dropzone/react-dropzone/blob/c36ab5bd8b8fd74e2074290d80e3ecb93d26b014/src/index.js#L807-L808
which triggers and error in vitest + happy-dom

Plain JS example

https://codesandbox.io/p/sandbox/silly-kowalevski-qjrmt6

const fileInput = document.getElementById("my-file");
fileInput.value = null;

doesn't throw errors in any browser

Thank you for reporting @csantos-nydig! 🙂

I believe it should be fixed now.
