This patch aligns WebKit with Gecko / Firefox and Web-Spec [1].

In 238774 at main, WebKit aligned with behavior for better compatibility but
it was not correct and clarified later to not throw error [2]. This PR is
essentially revert part of 238774 at main with update to align by not throwing error.
