`standaloneTheme.defines` Always return false.

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

• VS Code Version: Monaco Editor
• OS Version:

Steps to Reproduce:

The standaloneTheme.defines method always return false.

https://github.com/microsoft/vscode/blob/main/src/vs/editor/standalone/browser/standaloneThemeService.ts#L115-L117

public defines(colorId: ColorIdentifier): boolean {
    return Object.prototype.hasOwnProperty.call(this.getColors(), colorId);
}

https://github.com/microsoft/vscode/blob/main/src/vs/editor/standalone/browser/standaloneThemeService.ts#L75

private getColors(): Map<string, Color> {
    // ...
}

Because this.getColors() return type is a Map, so we should use this.getColors().has(colorId) in here.

@joaomoreno How can I verify this?

I think only in code:

	public defines(colorId: ColorIdentifier): boolean {
		return this.getColors().has(colorId);
	}
