Test Output still does not stream

[michaelharperSpectra]

go version go1.15.2 darwin/amd64
Visual Studio Code 1.51.0
Go extension version 0.18.1

settings.json =
{
"window.zoomLevel": 0,
"go.testTags": "unit regression acceptance allarchitectures",
"go.testTimeout": "24h",
"go.buildTags": "regression unit acceptance allarchitectures",
"terminal.integrated.shell.windows": "C:\Windows\System32\cmd.exe",
"go.testFlags": [
"-v"
],
"go.useLanguageServer": true,
"go.formatTool": "goimports",
"editor.codeActionsOnSave": {"source.organizeImports": true},
}

when pressing the run test button, output is not streamed in realtime to the output window: see issue #316

instead output shows Running tool: C:\Go\bin\go.exe test -timeout 24h -tags unit regression acceptance allarchitectures neo_test/test_suites/acceptance/bvt -run ^TestOutput$ -v until test is done and then dumps all information to console.
