[VSCode] Completion suggestions aren't refreshing during typing one by one character

[dos65]

Describe the bug

I stated digging a bit what is going on and noticed that in this case often doesn't ask LSP server for more completion even if prev result returns isIncomplete = true

Project setup:

// build.sbt

scalaVersion := "2.13.10"
libraryDependencies ++= List("com.typesafe.play" %% "play-json" % "2.9.3")

// src/main/scala/sample/sample.scala

package sample

class Sample {
  Json // <- issue here - no completions if you start typing `Json` one by one character
          //  in theory after having 3 char in query (`Jso@@`) there should be results  but there is no request to LSP 
  Json@@ // <- triggering it using shortcut after typing works well
}

It looks like a specific issue of vscode or metals-extension.
Extension version: Pre-release v1.20.9

Thanks for reporting! Looks like this is an issue in VS Code microsoft/vscode#155738

I see some workaround mentioned there.

oh, cool. It seems like in this case for VSCode we can return some fake completion like "complete typing ..." without text edit

Just confirming that I have tried this in another client (Neovim) and the issue doesn't exist there.
