Same thing with time zones like `America/Vancouver` where support for them has an effect on the test's outcome.

Sure, hence why I'd like to see separation similar to what already exists with [`test/intl402/`](https://github.com/tc39/test262/tree/main/test/intl402). Baseline Temporal is ISO8601 + UTC with offsets only.

> it isn't clear if this is something that the spec provides or that it is a property of [[IsHTMLDDA]]. Neither, the changes introduced by the slot are minimal: https://tc39.es/ecma262/#sec-IsHTMLDDA-internal-slot-to-boolean

Five years later I've just fixed a bug in our engine that would've been caught by these tests, maybe someone still wants to add them for future implementors :^)

@supercomputer7 please undraft the PR if you consider it ready for review :)

This has conflicts (again :cry:)

Investigate if the new results are correct according to the changed spec, and update the test if so. Otherwise, check if your implementation has a bug and file a spec...

These are different though and explicitly _not_ platform objects, only things defined via WebIDL are. They implement the _NativeError_ object structure from ES, as described in the spec I linked....

Yeah, feel free to point to the latest commit for now, but please tell upstream that changing a release after the fact is bad practice. :sweat_smile:

Please fix the linting errors.
