My project is using Angular6 with Infragistics.Web.ClientUI data source localization resources 18.2.72.

The data source of grid was got from API by an observable (about 100MB).

After destroy grid and clean data, the response data was keep in js heap.

On [rowsRendered] event, I use function ui.owner.getElementInfo([cell element]) to get column setting.

When comment out that line, the heap memory is cleaned.

I was post on https://ko.infragistics.com/community/forums/f/ignite-ui-for-javascript/121196/iggrid-observable-memory-leak 

Now it happen when i use $("").igGrid("option", "height", "300px");
