Overriding services no longer works

There is no regression. Overriding services works fine. e.g.

var openerService = {
	open: function() {
		alert(`open called!` + JSON.stringify(arguments));
	}
};

var model = monaco.editor.createModel('http://www.microsoft.com', 'plaintext');

var editor = monaco.editor.create(document.getElementById('container'), {
	model: model,
	glyphMargin: true,
	renderWhitespace: true
}, { openerService: openerService });

@alexandrudima It's great ! Besides it can give more information or documentation about overriding services?
