Development considerations Exposing the unit prop The unit prop is not exposed to assistive technologies by default. If you provide a unit abbreviation, you need to dissolve it in real text through the description prop. For example, if you use kmh, you can set the description prop to kilometers per hour. This way, the screen reader will read out the full text. Disabled state In general, you should prevent using the disabled state. Disabled elements are not reachable (focusable) anymore and can be missed by screen reader users. They can be confusing for sighted users as well by not pointing out why these elements are disabled. Limitations Due to the nature of Web Components and shadowDOM, there are limitations in the usage of some ARIA attributes if they try to set relationship between elements in different shadowDOM's or shadowDOM/lightDOM combinations.
