Icons are invisible on any WebKit browser

[LeonHeidelbach]

Hey, thank you for creating an easy to use API for Tailwind's hero-icons. I would really love to use your project, there is just one issue. None of the icons are visible when using a WebKit browser, like any browser on iOS or Safari on MacOS without applying a default width and height. The lucide icons pack does not have this issue since they apply the height and width attribute to each icon and set the default value to 24. Setting the viewBox value to 0 0 24 24 does not seem to be enough. It is weird that this is only an issue on WebKit browsers though.
