The WHATWG File System spec has been updated to make the `size`, `position`, and `data` members of the `WriteParams` dictionary non-nullable. Previously these were marked as nullable (`?`), but the `write()` algorithm never handles null values. Making them non-nullable means passing null will now throw a TypeError at the WebIDL boundary, which is the correct and intended behavior. Spec change: https://github.com/whatwg/fs/pull/182 Related issue: https://github.com/whatwg/fs/issues/181 WPT tests: https://github.com/web-platform-tests/wpt/pull/58156 Please update the WebKit implementation so that passing null for `size`, `position`, or `data` in `WriteParams` throws a TypeError.
