[Meta] Discussion topics for the TC39 plenary of June 2022

[leobalter]

Here is a tentative list for the topics we intend to discuss at the TC39 plenary in June 2022:

• (30m) Errors across the ShadowRealm boundary
• HTML Integration: status and open questions
  • Blocking: needs resolution on the current Realm
  • Should HostImportModuleDynamically provide a referencing script? #363
  • Needs resolution on Resource Timing API (needs link)
  • Should performance be exposed? (needs link)
  • Should rejected promises cause an event to be fired in the principal realm? (needs link)
• Normative PR Normative: GetFunctionRealm may throw on revoked proxies #356
• Update on IsHTMLDDA: Disallow IsHTMLDDA wrapping #357

Tentative or for the plenary in July 2022:

• importValue: How to import a module with no exports? #364
• Inspecting errors thrown from ShadowRealm #353

Maybe #351 is worth a time slot too?

Interest in #364

[leobalter]

@Jack-Works I believe we can benefit of discussing more a design for #364 before a TC39 plenary. I'm happy to mention the problem but it seems early for a solution as it's being proposed there.

@legendecas I believe the design for #364 should also provide a resolution for #351.

I think these both topics can benefit of a design exercise and we discuss them at the Plenary in July. I have no objections to them, but the current topics listed might require extra time for the plenary next week.

I'm confused about the decision to mark the one purely editorial issue as blocking. All of the other issues are about normative semantics, which is surely more blocking as far as shipping in a browser goes.

The biggest piece of missing work seems to be specifying [Exposed=ShadowRealm] in WebIDL and annotating the appropriate web specs with it.

FWIW, whatwg/html#7591 can be one of the discussion links for the topic "Should rejected promises cause an event to be fired in the principal realm?"
