Describe the bug

Before you could customize a <select>, if you put things like an image or SVG into the <option> element, the browser would ignore them, but Svelte throws an error:

With the release of Chrome 135, the <select> element can now be customized using CSS and supports rich HTML content. Browsers that implement appearance: base-select will eventually support this feature.

Reproduction

This custom select example is valid in Chrome 135 and later versions.
