Hi,
if you create a html web resource and on the html webresource post required data(FetchXml, LayoutXml, EntityName, DefaultAdvFindViewId, ViewType)
to
AdvancedFind/fetchData.aspx than grid is appear correctly,
but if html web resource is deployed on the Crm Entity Form than Command Bar menu switch to advanced
Find Ribbon menu :(
