"Continue with Default Image" button doesn't work when build is still in progress

[jankeromnes]

Bug description

When creating a workspace, and it runs a Docker build, you can not skip it while the build is still running (Continue with Default Image button does nothing).

However, if the build fails, then the button works.

Steps to reproduce

• Open https://github.com/jankeromnes/gitpod-build-error
• While the build is in progress, click on Continue with Default Image. It doesn't work.
• When the build fails, then the button works.

Expected behavior

It should work in both cases.

Potentially relevant: The server pod seems to log this whenever I click on Continue with Default Image while the build is still running:
