Raises bundle/js/__tests__/wpt from 161 to 169 passing tests (out of 180)
with zero unit-test regressions, through a series of targeted spec-
correctness fixes.
Fetch: real Subresource Integrity verification (sha-256/384/512 with
strongest-metadata selection and base64+base64url decoding); 421
Misdirected Request retry on a fresh TCP connection per Fetch \u00a74.5;
duplex: 'half' enforcement for streaming request bodies; reject_with_error
now surfaces the actual JS exception value instead of an uninitialized
one.
URL: Windows drive-letter normalization (/w|/ -> /w:/); file-URL host
preservation when path has a drive letter; USVString conversion on
constructor input (lone UTF-16 surrogates -> U+FFFD); spec-correct port
setter whitespace handling; /.-sentinel stripping on set_hostname;
blob-URL origin null-opacity for non-HTTP(S) inner URLs; trailing-space
percent-encoding on non-special opaque paths.
Streams: implement type: 'owning' with structural-transfer on
controller.enqueue(chunk, {transfer}); fix reentrancy borrow conflict in
byobRequest when user code patches Object.prototype.then mid-enqueue;
Rust-side direct-drain of closed ReadableStream queues so
Response.text()/.json() etc. resist Object.prototype.then pollution.
WebCrypto: subtle.digest snapshots input bytes synchronously at call time
(no longer at first poll), so post-call buffer mutations can't alter the
result; detached BufferSource is treated as empty per WebIDL. TextDecoder
got the same detached-buffer treatment.
Also: console counters/timers moved from thread_local! to
Ctx::store_userdata so multiple contexts don't conflate state.
