[Bug]: Julia Extension REPL Terminal not restored after code-server window reload

Is there an existing issue for this?

• I have searched the existing issues

OS/Web Information

• Web Browser: Chrome 103
• Local OS: Windows 10
• Remote OS: Ubuntu 18
• Remote Architecture: amd64
• code-server --version: 4.5.1

Steps to Reproduce

1. open code-server
2. install Julia v1.7.3 (latest stable) on the remote
3. install Julia extension (currently v1.6.28, can also reproduce with v1.6.24)
4. start Julia REPL
5. start normal (e.g. bash) session. Check Julia process id in the list of processes (there would be two Julia processes: one running LanguageServer main.jl, the REPL one runs terminalserver.jl).
6. reload code-server window/tab

Expected

Upon reload Julia REPL is preserved. It was working with VS Code 4.2.0 (4.3.0 and 4.4.0 haver other problems in my setup, so I cannot test them) and Julia extension 1.6.24.

Actual

Julia REPL is not in the list of terminals, while the old Julia REPL process (the one that runs terminalserver.jl) is still running.

Are you accessing code-server over HTTPS?

• I am using HTTPS.

@benz0li are you able to reproduce this?

Yes. Currently, this can be reproduced at https://demo.jupyter.b-data.ch with image Julia (base:latest) + code-server (=registry.gitlab.b-data.ch/julia/base:1.7.3 (code-server v4.5.1, Julia v1.7.3, Julia extension v1.6.28)).

It is not working with registry.gitlab.b-data.ch/julia/ver:1.7.2 (code-server v4.4.0, Julia v1.7.2, Julia extension v1.6.17) either.

It was last working with registry.gitlab.b-data.ch/julia/ver:1.7.1 (code-server v4.0.1, Julia v1.7.1, Julia extension v1.5.10) in my case.
ℹ️ I didn’t release Julia images with code-server v4.1.0 or v4.3.0 and I skipped over v4.2.0 due to issues.

When I start a new Julia REPL:

[IPC Library: Pty Host]  WARN Shell integration cannot be enabled for executable "/opt/julia/bin/julia" and args [
  '-i',
  '--banner=no',
  '--project=/opt/julia/local/share/julia/environments/v1.7',
  '/opt/code-server/lib/vscode/extensions/julialang.language-julia-1.6.17/scripts/terminalserver/terminalserver.jl',
  '/tmp/vsc-jl-repl-c60ae286-d040-431f-a691-e903b1172776',
  '/tmp/vsc-jl-cr-b45e317b-56ca-4d6c-a10c-fddc98d8ea27',
  'USE_REVISE=true',
  'USE_PLOTPANE=true',
  'USE_PROGRESS=true',
  'DEBUG_MODE=false'
]

Then, after reloading the code-server browser tab/window:

[nothing relevant]

And the Julia REPL is gone.

(code-server v4.5.1, Julia v1.7.3, Julia extension v1.6.28)

---

With code-server v4.0.1 I get the [IPC Library: Pty Host] INFO Persistent process "2": Replaying 264 chars and 1 size events message and the Julia REPL is restored.
