WebIDL integration #6

Closed petamoriken closed 4 days ago

petamoriken commented 4 months ago

DOMException does't have [[ErrorData]] internal slot. This means that we may need to work on the WebIDL side.

The slot is mandated by the JS spec, so if WebIDL lacks that slot then it should indeed be added.

I'm glad to see this issue filed and solution presented. Let's try to get a WebIDL PR out there before Stage 2.7.

Closing this, since https://github.com/whatwg/webidl/pull/1421 is filed and conceptually approved.
