Prebuild Loading Screen doesn't auto progress when done

[svenefftinge]

Bug description

When starting a workspace on which a rebuild is running, the screen blocks and shows the log output of the rebuild.
When done it should automatically progress to starting a new workspace.
It doesn't (always?) do that when the time spent on that page was long.

Steps to reproduce

start a workspace on a commit that is being prebuild and the prebuild takes a few minutes

I just experienced a long wait with https://gitpodio-gitpod-sdmofwboptx.ws-us38xl.gitpod.io/, with instance ID 22775e2b-8c57-4be5-9908-363e7838350d.

4m 11s to initialize (according to web app logs).

Workspace logs

2022-03-18 19:56:40.000 GMT supervisor: workspace content available
At this point the IDE takes over and the workspace is usable.

4m 5s to restore content (according to workspace logs). 😬

Next steps:

• Benchmark times (1) to transfer the tar file from GCS (2) to extract the TAR on the node to the pod's /workspace
• Add logging and traces for both events (so we can more easily capture for the future)

The PVC work that we're exploring should help with this, removing from scheduled work for now.

I don't think PVC work would help here. This seems like webapp related issue potentially?
Though we did fix a bunch of issues related to prebuilds recently, and I am wondering if this is even still happens?
@jmls are you still experiencing this by any chance?
