- @westonruter shared that the change looks close to being ready, but an unexpected E2E test failure still needs investigation. @mukesh27 shared that the implementation looks solid overall, and @westonruter mentioned he had merged the latest trunk changes and planned further debugging, including testing behavior with unminified scripts if the failure persists.

@SarthakJaiswal shared that he has been working on PR #2321, plans to review feedback, and will implement required changes soon, while also asking whether there are additional polishing improvements worth considering.

@mukesh27 asked who would be attending WordCamp Asia this year. @westonruter shared that he is looking forward to the Core Performance table at Contributor Day and noted that, since the conference will correspond with WordPress 7.0, either team could land some very early things for WordPress 7.1 or focus on Performance Lab.
