Thanks for updating these. We won't be able to land this without a workerd bump to a version that includes the new flag: https://github.com/cloudflare/workers-sdk/actions/runs/8138977567/job/22241061215?pr=5148#step:8:549

[mrbbot]

I'm not actually sure this needs a changeset. This PR is only changing tests.

[dom96]

I'll keep it since this PR also updates workerd to the version that requires the new compat flag.

[penalosa]

Could you add another changeset for that bump?

[dom96]

@mrbbot I thought that may be the case, here is a bump in the workerd repo cloudflare/workerd#1761
