Reopen in container spins indefinitely

I've tried this both with the sample repo, and my [own repo here](https://github.com/alexwaibel/momentum-mod-website/tree/feat/devcontainer) and in both cases VS Code spins indefinitely when selecting "Reopen in container". Under output > window I see a lot of these messages:
`2024-02-23 18:10:04.420 [info] [LocalProcess0][resolveAuthority(dev-container,1)][119007ms] waiting...`

Not sure if that's the best error message but that's the most descriptive one I could find in all the output windows. You can repro this by following this README's instructions up to and including these steps:
1. `code codespaces-multi-dev-container/container-1-src`
2. Click the "Reopen in Container" button in the notification that appears
