Aspire dashboard doesn't start first time inside Dev Container

[erwinkramer]

Is there an existing issue for this?

• I have searched the existing issues

Describe the bug

Inside a dev container, when starting a debugging session. it opens http://localhost:15088/login?t=..., this one keeps loading and never actually completes loading. During the same session, if i open another tab in the browser and paste the same URL, it works (after about 2 minutes).

Looks related to #2422.

Expected Behavior

Should complete loading (or maybe wait before opening in the browser when it's really ready for it).

Steps To Reproduce

Clone https://github.com/erwinkramer/bank-api and run the dev container. Then start the launch config C#: App Host Debug (via Aspire).
