watchedFiles fails to watch nested files on linux

[justinmk3]

Problem

recursive file watching doesn't work on linux since vscode 1.67 ...?

this test fails:

  1) CloudFormation Template Registry
       adds dynamically-added template files with yaml and yml extensions at various nesting levels:
     Error: Timed out waiting for registry to populate. Actual item count: 1. Expected item count: 2.

comparing logs shows that we don't get an event for the nested file:

- CloudFormationTemplateRegistry: manager detected a new file: .../src/testFixtures/workspaceFolder/1/nested/test.yaml
  CloudFormationTemplateRegistry: manager detected a new file: .../src/testFixtures/workspaceFolder/1/test.yml

Solution

1. find root cause
2. report upstream?
