We fill these overload sets from vectors, which means that by the time
we iterated over them, any semblance of their original ordering was
lost. Their ordering is important, because we invoke
define_native_function() for them which eventually stores ordered
properties.
This should not be an issue as long as iterating over a HashMap that was
filled in exactly the same way results in the same ordering. However,
HashTable utilizes kmalloc_good_size() to determine a good allocation
size - and the implementation for kmalloc_good_size() on Linux and macOS
differs, causing a different capacity and ordering on those platforms.
This was not caught by CI, because we run that with sanitizers enabled
which overrides malloc_good_size() on macOS, resulting in the same
behavior as on Linux.
Change the overload sets to be OrderedHashMaps instead and rebaseline
the failing test.
This matches the prototype attributes.
Used by https://chatgpt.com/, where it runs this code:
```js
CSS.supports('animation-timeline: --works')
```
If this returns false, it will attempt to polyfill Animation Timeline
and override CSS.supports to support Animation Timeline properties.
