Status: RESOLVED DUPLICATE of bug 1315135

(Firefox :: Untriaged, defect)

Steps to reproduce:

Heads-up that we've stopped special casing Regexp in the WebIDL spec as of
https://github.com/heycam/webidl/commit/bbb2bde

Here's a diff of what that looks like in the rendered HTML spec:
[diff]: https://services.w3.org/htmldiff?doc1=https%3A%2F%2Fcdn.rawgit.com%2Fheycam%2Fwebidl%2F001ba52%2Findex.html&doc2=https%3A%2F%2Fcdn.rawgit.com%2Ftobie%2Fwebidl%2F00b9786%2Findex.html

That means that the following algorithms now allow regexes in places where they previously didn't:

1. to convert an ES value to a dictionary: https://heycam.github.io/webidl/#es-dictionary
2. to convert an ES value to a sequence: https://heycam.github.io/webidl/#es-sequence
3. to convert an ES value to a union type (step 5 and 11): https://heycam.github.io/webidl/#es-union
4. the substeps of step 11 of the overload resolution algorithm: https://heycam.github.io/webidl/#es-overloads

There are also some modifications to the section on User objects implementing callback interfaces:
https://heycam.github.io/webidl/#es-user-objects

I opened an issue against web-platform-tests's testharness to account for these changes:
https://github.com/w3c/testharness.js/issues/223

Please raise any concerns by opening an issue against the spec:

Thanks.

Tobie, thank you for filing this!

In the future, can you file IDL-related bugs in Core:DOM and cc me?
