Issues with w2grid autoLoad

[gitgitwhat]

Short description
There are a few issues with w2grid and loading from remote sources. First, I can't seem to get 'Load More' more to show. I've studied this example (http://w2ui.com/web/demos/#/combo/9) but there doesn't seem to be anything different than what I'm doing so not sure how to make the 'Load More' show. Second, multiple requests are made initially when the page loads. Third, I have to use preventDefault() in onLoad so that I can process the returned data or else the grid gets cleared. I don't know if the two later issues are intended behaviors but it seems off.

Here are the console.trace() during page load for the onRequest method. I don't understand why it is being triggered so many times.

Here is a reduced example based on the example cited above. I've purposely limited the number of rows just to try to get the 'Load More' link to show but it never does.

Steps to reproduce or sample

function AddRows(json) {
   //...
   //parse and push records
   //...
   w2ui['grid'].refresh();
}

		let config = {
			layout: {
				name: 'layout',
				panels: [
					{ type: 'main', style: gStyle, content: 'main'}
			        ]
			},
			grid: {
				name: 'grid',
				url: cmd,
				autoLoad: false,
				limit: 3,
				columns: [
					{ field: 'id', text: 'id', hidden:true },
					{ field: 'title', text: 'Title', size: '100%' },
				],
				onRequest: function(event) {
                                        //Modify the url by adding some custom parameters
					event.url += mod_request;
				}, 
				onLoad: function(event) {
                                        //Without this, the grid won't show any records.
					event.preventDefault();
					AddRows(event.xhr.responseText);
				}
			}
		}

		$().w2layout(config.layout);
		w2ui.layout.html('main', w2ui['layout']);

		$().w2grid(config.grid);
		w2ui.layout.html('main', w2ui['grid']);
		w2ui.grid.autoLoad = false;
		w2ui.grid.skip(0);
