api.ScreenOrientation - `unlock()` incorrectly described as throwing exceptions

What type of issue is this?

Incorrect support data (ex. Chrome says "86" but support was added in "40")

What information was incorrect, unhelpful, or incomplete?

The 'unlock()' method is described as 'partially compatible' and 'Always throws NotSupportedError' on https://developer.mozilla.org/en-US/docs/Web/API/ScreenOrientation.

However, unlike lock(), unlock() does not involve a Promise and is not described as throwing exceptions in the spec. Furthermore, real-life testing shows that no exceptions are generated in current browsers including Chrome and Firefox.

Possibly this discrepancy was due to an assumption that it behaves the same as lock() — otherwise, I am rather at a loss as to why the exception cannot be observed on production desktop browsers.

This error is also visible on https://developer.mozilla.org/en-US/docs/Web/API/ScreenOrientation/unlock as well as https://caniuse.com/mdn-api_screenorientation_unlock

What browsers does this problem apply to, if applicable?

Chromium (Chrome, Edge 79+, Opera, Samsung Internet), Firefox, Safari

MDN metadata

Start with the ScreenOrientation compatibility data associated with the MDN ScreenOrientation and ScreenOrientation/unlock pages, then compare the unlock() behavior with the relevant specification and current browser behavior. Update the support information so it no longer claims that unlock() always throws NotSupportedError, and verify that both linked MDN pages and the caniuse data reflect the correction.
