Upcoming HTML standard issue triage meeting on 5/4/2023

[past]

Today we held our biweekly triage call (#9132) and I will post the meeting notes there in a bit. The next one is scheduled for May 4, 9 am PDT. Note that this is 2 weeks later in an America+Europe friendly time.

People interested in attending the next call please respond here or reach out privately to me or the spec editors. We will be tagging issues for the next call again using the agenda+ label in all WHATWG repos and we would like to invite anyone that can contribute to said issues to join us.
