Usage example near the top of the spec repeats the observer.observe code – https://w3c.github.io/long-animation-frames/#example

const observer = new PerformanceObserver(function(list) {
    for (const entry of list.getEntries()) {
        // Process long task notifications:
        // report back for analytics and monitoring
        // ...
    }
});
// Register observer for previous and future long task notifications.
observer.observe({type: "long-animation-frame", buffered: true});
// Long script execution after this will result in queueing
// and receiving "long-animation-frame" entries in the observer.

// Register observer for previous and future long animation frame notifications.
// After this, long periods where the main thread is busy will result in queueing
// and receiving "long-animation-frame" entries in the observer.
observer.observe({type: "long-animation-frame", buffered: true});

Presume this is a typo?

Good eye! Interested in creating a PR? The comments are minimally different... I think the second is slightly cleaner?

Will do
