Submenu with hash in hraf does not toggle in mobile view

If you build a menu with submenus where the parent menu is a custom link containing a hash (#) as link target, the submenu won’t toggle (open) if you click on the parent (the burger menu setting is ‘display submenu items on click’).

The submenu toggles as intended if the parent menu item is a page or contains a local target like #top.

The issue stems from avia.js starting from line 1861

		//toogle hide/show for submenu items
		$('.html_av-submenu-display-click').on( 'click', '.av-width-submenu > a', function (e) 
		{ 
			e.preventDefault();
			e.stopImmediatePropagation();
			
			var clicked = $(this), parent  = clicked.parents('li').eq(0);
					
			parent.toggleClass('av-show-submenu');
			
			if(parent.is('.av-show-submenu'))
			{
				parent.children("ul.sub-menu").slideDown('fast');	
			}
			else
			{
				parent.children("ul.sub-menu").slideUp('fast');	
			}
			
		});

The on.click event simply does not trigger if the anchor contains only the hash

<a href="#"> does not trigger on.click
<a href="#top"> does trigger on.click
