Review past action items

Carryovers from last time

  • Waiting to get review on a Gecko patch that implements what would be my formal proposal, in order to confirm it is web-compatible.

• <input type=color> enhancements

Action Items

• None

Minutes

Topic: 1a

• Keith: Updated tests for Invoker Buttons along the lines of the latest proposal.
• Anne: Will we regret not overriding the default type?
• Keith: The fallback in older browsers is quite bad. E.g., a website asks “Do you want to delete this?” and then you click the “More info” button and it ends up deleting.
• Luke: Does this mean we can never add a new type?
• Keith: Potentially.
• Anne: I wonder if we should investigate that a bit more to see if we can change the fallback.
• Luke: Perhaps we should require an explicit type attribute?
• Keith: I think that is a somewhat artificial restriction.
• [Lots of unminuted discussion to figure out if we can do better.]
• Rough proposal to do better:
  • Require the type attribute for now with command when inside form.
  • A command without a type attribute when inside a form also changes the default, but the command doesn’t work. (Going from non-functioning to a command seems better than going from submit to command in the future.)
  • In the (far) future we can remove the type attribute requirement.
  • Outside form we default type to button straight away if there’s a command attribute.
  • Separately investigate changing the invalid default for the type attribute.

Topic: 2a

• Emilio will work on an update.

Topic: 2b

• Working on Gecko patch and want to wait to see how well that works before moving forward.

Topic 3 (opener relationship)

• Anne and Olli said a bunch of unminuted words, but largely-but-not-completely agree. Perhaps noopener as additional value makes sense for bfcache.
• Olli: what about COEP?
• Anne: that is a good question, it could in theory maybe combine as it’s close in strictness to COOP: same-origin.

Topic (input type color enhancements)

• Anne: I proposed adding alpha and colorspace attributes to input.
• [Some unminuted discussion about tradeoffs made.]
• Luke: ship it
• Olli: looks quite reasonable, will take a look
