load and idle event never triggered when a source loading fails

[oterral]

It seems that when source fails to load that the load and idle event are never triggered.
I suppose that if tiles.json requests fails the map should just ignore them and triggers the events properly.

maplibre-gl-js version: 5

browser: all

Steps to Trigger Behavior

1. Open https://codepen.io/oterral/pen/YPKgyGq
2. An alert box should appear for the 'load' and 'idle' event but notthing happens

Link to Demonstration

Open https://codepen.io/oterral/pen/YPKgyGq

or try this:

// Initialise the map
const map = new maplibregl.Map({
  container: 'map',
  style: "https://vectortiles.geo.admin.ch/styles/ch.swisstopo.leichte-basiskarte_world.vt/style.json",
  center: [7, 47],
  zoom: 10
});

map.on('load',()=> alert("loadevent"));
map.on('idle',()=> alert("idleevent"));

Expected Behavior

idle and load events are triggered

Actual Behavior

idle and load events are not triggered

Has this been changed in recent versions or is this the behavior since version 1.x or 2.x?

I believe this has been the behavior since 1.x. Do we think the load event should be published if loading fails? It does seem the idle event should be at least. There's also an error event that should be published; is that happening for you @oterral ?

[oterral]

@neodescis yes the error event is triggered. For sure if nothing happens on the map the 'idle' should be triggered . As a user that doesn't have the hand on the style I would also expect that 'load' event is triggered every time i load the map, whatever if a source loading have failed otherwise I can't rely on it.
