API: "active-leaf-change" event is sometimes triggered twice

Steps to reproduce

I wrote this small test plugin:

'use strict';

var obsidian = require('obsidian');

class MyPlugin extends obsidian.Plugin {

	async onload() {
		this.app.workspace.on("active-leaf-change", () => {
			console.log("Active leaf changed!")
			new obsidian.Notice("Active leaf changed!");

module.exports = MyPlugin;

With this plugin enabled, try to switch between different files in the navigation menu. In addition to switching between markdown files, try also swithing to images and audio files.

Expected result

The event should be triggered only once. I.e. my test plugin should display only one “Active leaf changed!” Notice.

Actual result

The event is sometimes triggered twice. I.e. my test plugin displays “Active leaf changed!” Notice twice.

Also, every time I start (or restart) Obsidian, the event is triggered twice instead of once.
