Steps to Reproduce

(1) Open pwsh console (or in my case an app hosting PowerShell Core).

(2) In VSCode, attach to this process for PowerShell debugging.

(3) In pwsh, invoke the attached script debug-4489.far.ps1 -- it sets some breakpoints for testing.
debug-4489.far.ps1.zip

(4) In pwsh, type and invoke test1 -- it breaks into VSCode debugger.

(5) In VSCode terminal type $host and hit Enter.

Expected result
VSCode evaluates the statement $host and prints the output (the host properties in this result).
It definitely used to work like this some versions ago.

Actual result
Nothing happens in the terminal until we go to the attached pwsh console and hit Enter there.
(Why? And how a user is supposed to know this?)

Riprodurre con debug-4489.far.ps1 collegando VS Code a pwsh, invocando test1 e immettendo $host nel terminale di VS Code. Tracciare il flusso della console del processo collegato e dell’input del terminale; è completato quando $host viene valutato e stampa le proprietà dell’host senza premere Invio nella console pwsh collegata.
