Cannot expand left panel if a direct link to a workspace is using

[gorshkov-leonid]

Describe the bug

Prehistory of my case:

it is related to eclipse-theia/theia#8292.
But because workspace-loader was replaced with che-dashboard this question became actual again.
I need to share a link to a specific file(with line and column) in workspace. The problem was solved with a custom plugin that reads query parameters and uses Theia API to open files. The base of the solution was the ability to pass query parameters to the plugin. It was possible with URIs like /workspace-loader/lego/temp-prj?f=/projects/22.txt&l=61&c=421&uid=42

But now there is no workspace-loader and I use link from workspace dto. This works as well as earlier, except expanding left panel.

Exactly the problem is in the link that client side got from server via /services
I expect link is https://che-namespace.k8s.managed.cloud/dashboard/#/ide/admin/temp-prj. But link is: http://che-host.namespace.svc:8080/dashboard/#/ide/admin/temp-prj

Che version

7.34

Steps to reproduce

• https://server8wkx32v7-jwtproxy-server-4402.k8s.managed.cloud/#/projects
• Press "Expand navigation bar" button
• AR: Opened link http://che-host.namespace.svc:8080/dashboard/#/ide/admin/temp-prj
  

Expected behavior

As in 7.15

• https://server71ljacf3-jwtproxy-server-4402.k8s.managed.cloud/#/projects
• Press "Expand navigation bar" button

When clicking on show-navbar button, Che-Theia sends a message to the dashboard.
I suppose this behavior has been changed in the new dashboard.
@sleshchenko could someone from your team look at this?

@azatsarynnyy according to the shared context, I think it's the theia bug and it uses internal CHE URL (CHE_INTERNAL_URL) but should use public (CHE_URL).

We'll look at it for 7.39.

I believe there's not much sense to work on that issue for us. Considering there's no IDE IFRAME in the Dashboard anymore.

but IMHO anyway we would need a way to open dashboard from the Editor
