getState on hidden column with a filter

Hi,
This snippet is working perfect but not on my environment: http://webix.com/snippet/797be341

datatable.getState() fails when the hidden column has a filter. I’m using webix 1.10

it fails at line 16611 node is null: getInputNode:function(node){ return node.firstChild.firstChild; },

Why is it working with the snippet ??

In fact, I’ve just noticed that this is not working with IE 9 /10 /11

I can confirm the issue, combination of filter and hidden column doesn’t work well.
It will be fixed in the oncoming update.
