Steps to Reproduce

Run fiddle

https://zkfiddle.org/sample/hn91qh/3-listbox-za11y-event-catch

Type a value in any input components in first listbox

Use the left arrow to move the caret at a different position inside of the input element.

Current Result

focus is removed from the edited input

focus is added to the navigation anchor based on the parent listcell

Expected Result

while editing an input-based widget, directional arrows should be used for caret position inside the widget

Debug Information

starts from zA11y listcell doKeyDown_ override

triggers visibleSibling._focusContent()

Workaround

Prevent event propagation at inputWidget level:

	<script><![CDATA[ 
	zk.afterLoad("zul.inp", function () {
	    var _xInputWidget = {};
	    zk.override(zul.inp.InputWidget.prototype, _xInputWidget, {
	        doKeyDown_: function (evt, simulated) {
	        	var key = evt.key;
				switch (key) {
					case 'ArrowLeft':
					case 'ArrowRight':
					case 'ArrowUp':
					case 'ArrowDown':
						evt.stop({propagation:true});
						break;
				}
				var result = _xInputWidget.doKeyDown_.apply(this, arguments);
				return result;
	        }
	     });
	});
]]></script>
