            Bug ID: 218018
           Summary: Error handling for ISO-2022-JP is incorrect
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: DOM
          Assignee: webkit-unassigned at lists.webkit.org

See tests added and corrected in https://github.com/web-platform-tests/wpt/pull/26158. In particular it seems 0x0E, 0x0F, and 0x1B are not treated as errors which could lead to XSS in badly constructed sites.

(I think a similar problem applies to form submission, but I didn't write tests for that.)

(There's also some specification changes for this: https://github.com/whatwg/url/pull/558 and https://github.com/whatwg/encoding/pull/238.)
