No documentation is produced in completion item during test run

Does this issue occur when all extensions are disabled?: Yes/No

• VS Code Version: 1.68.1
• OS Version: macOS 12.4

Steps to Reproduce:

1. Generate a completion item in an LSP sample where documentation is included in the items.
2. Write a test case expecting documentation in the completion items.

Our LSP extension adds documentation to the completion items. The documentation can be seen when running the extension manually.

      const documentation: MarkupContent = {
        kind: "markdown",
        value: [
          `## Module: ${output.source}, Output: ${output.key}`,
          `${docString}`,
          `${moduleRepoDocString}`,
          `${internalLineDocString}`,
        ].join("\n"),
      };

      return {
        label: `$workitem.${output.source}.outputs.${output.key}`,
        kind: CompletionItemKind.Value,
        data: index + 1,
        preselect: true,
        sortText: "1" + String(index + 1).padStart(4, "0"),
        detail: "Module-level output",
        documentation,
      };

However, the completion items produced during a test run have everything except the documentation:

{"label":"$workitem.bp-iks-vpc-gen2-cluster.outputs.cluster_id","kind":"Value","detail":"Module-level output","documentation":{},"sortText":"10001","preselect":true,"insertText":"$workitem.bp-iks-vpc-gen2-cluster.outputs.cluster_id"}

The behavior you are seeing is expected. The server fills in details and documentation lazily on a resolve call only for the item selected in the UI. You either need to trigger the resolve call via another command or fill in the properties during the normal completion call.

See https://github.com/gee4vee/lsp-testing-bugs/blob/d2da939e972c75d6e65b794b7666f2a3b0c8218a/server/src/server.ts#L212

I will close the issue. Please ping if something is still unclear.
