Steps to Reproduce:

1. Install Jupyter extension
2. Make a dummy extension and install it:

export function activate(context: vscode.ExtensionContext) {
		context.subscriptions.push(
			vscode.languages.registerSignatureHelpProvider('python', {
				provideSignatureHelp(document, position, token, context) {
					return {activeParameter: 0, activeSignature: 0, 
					signatures: [{
						label: "foo",
						parameters: [{label: "v"}],
						documentation: "aaaa",
					}]};
				},
			}, {triggerCharacters: ["("], retriggerCharacters: [","]}));
		}

	"activationEvents": [
		"onLanguage:python"
	],

2. Create Interactive Window
3. Enter import datetime; datetime.date(
4. Nothing shows up
5. Press Ctrl+Shift+Space
6. Nothing shows up
7. The signature help works on new .py files though, just not in the interactive.
