Setting maxbounds on map creation throws warning

• I’ve looked at the documentation to make sure the behavior is documented and expected
• I’m sure this is a Leaflet code issue, not an issue with my own code nor with the framework I’m using (Cordova, Ionic, Angular, React…)
• I’ve searched through the issues to make sure it’s not yet reported

Steps to reproduce Steps to reproduce the behavior:

• create a map while setting maxbounds
• on loading the map it throws a warning

listener not found
_off @ leaflet.js:590
off @ leaflet.js:499
setMaxBounds @ leaflet.js:3422
initialize @ leaflet.js:3114
NewClass @ leaflet.js:302
createMap @ leaflet.js:4717
(anonymous) @ VM8861 about:srcdoc:231

Expected behavior

It should not throw a warning

Current behavior

Environment

• Leaflet version: 1.8.0 (the identical code with 1.7.1 doesn’t throw a warning)
• Browser (with version): Latest Chrome and Firefox
• OS/Platform (with version): Windows 10

Additional context

Minimal example reproducing the issue

var map = new L.Map('leaflet', {
	layers: [
		new L.TileLayer('https://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png', {
			'attribution': 'Map data © <a href="https://openstreetmap.org">OpenStreetMap</a> contributors'
		})
	],
	center: [-35.149, 149.08013],
	maxBounds: [
		[0, 101.25],
		[-55.77657, 168.75],
	],
	zoom: 7
});

Please create an example using https://leafletjs.com/edit.html or any other jsfiddle-like site.

• this example is as simple as possible
• this example does not rely on any third party code

Is no problem of Leaflet. Leaflet.Sleep has many usages of off() after once(), which will always throw listener not found because once has already removed the listener.

Thanks, I can confirm that the fix works for me. Closing.
