Fix missing layers in layer menu on refresh

[crisner]

There was a change I made on one of my previous PRs that fixed some errors by adding a check to when the 'moveend' event was triggered. This seems to have affected how the layers were displayed in the layers menu when the page was refreshed. Sometimes there were layers missing from the layers menu when it should have been there.

leaflet-environmental-layers/src/util/layersBrowser.js

Lines 470 to 477 in c69ad9a

	map.on('moveend', function() { // Update layer list on map movement
	if (isPageRefreshed < 2 && window.performance.navigation.type !== 1) {
	isPageRefreshed++; // Track page moveend events to prevent errors on map.removeLayer when a page is reloaded
	}
	if(isPageRefreshed > 1) {
	self._hideElements(obj, data, layerName, elements, true);
	}
	});

Ah, is it possible this was related to #376 ?Thank you!

This was not implemented into the one-liner usage in the version used in plots2. Also, this deals with overlays and does not affect baselayers. 😃
