Steps to Reproduce:

1. Create a test.code-workspace workspace file with the following

{
  "folders": [
{
  "folders": [
    {"path": "0"},
    {"path": "1"},
    {"path": "2"},
    {"path": "3"},
    {"path": "4"},
    {"path": "5"},
    {"path": "6"},
    {"path": "7"},
    {"path": "8"},
    {"path": "9"},
    {"path": "10"}
  ],
	"settings": {}
}

With more root folders, the order is completely unpredictable, but always consistent.
