/**
 * `WakeLock` uses the [WakeLock API](https://developer.mozilla.org/en-US/docs/Web/API/Screen_Wake_Lock_API) to ensure the screen does not turn off when viewing the page on supported devices. Use your best judgement for when this is necessary, for example, if you have a timer that needs to stay on, or you are displaying a QR code.
 *
 * - WakeLock can be toggled with a `trigger`, or will be requested if the element has a `locked` attribute when connected.
 * - Use `content` and `swap` elements to adjust the UI based on the current state.
 * - `request` and `release` methods are provided to set the WakeLock with JavaScript.
 * - `trigger` is disabled if not supported.
 * - WakeLock is released when the element is removed from the DOM.
 *
 * `auto-lock`
 *
 * - By default, the WakeLock will be released when the tab is not active. Use the `auto-lock` attribute to automatically request the WakeLock when the user views the tab again.
