Hash is not synced with map position when terrain is enabled.

[HarelM]

maplibre-gl-js version: 4.3.1

browser: Chrome

Steps to Trigger Behavior

1. npm run start
2. http://localhost:9966/test/examples/3d-terrain.html
3. Move the map a bit
4. Wait 1 second
5. In the console of the browser execute map.getZoom()
6. Compare the zoom value to the addressbar hash value - they are different buy just a bit.

Expected Behavior

Zoom in the address bar and in the console (current map state) should be the same after the map had stopped moving.

Actual Behavior

The zoom values are different.

This is related to the fact that we are recalculating the zoom using a moveend event: here:

maplibre-gl-js/src/ui/handler_manager.ts

Lines 522 to 526 in 5ab0099

	this._map.once('moveend', () => {
	this._map._elevationFreeze = false;
	this._terrainMovement = false;
	tr.recalculateZoom(map.terrain);
	});

This was introduced to solve this issue:

• Zoom center not under cursor when terrain is on #1024

Using this PR:

• Fixes zoom not under mouse #1977

I think there was another issue related to this code, but I can't find it ATM...

I think the solution is to the _fireEvents method, there's a section at the end with endAnimation, which fires this moveend event, so it might be the right place to add the logic, I'm just not sure what it will break...
