Standalone VF page with a managed component not working on IE 11

Hello all,

We developed a VF page to override a custom object's New & Edit buttons. It uses a managed component (address validation component of Informatica package) & code structure is as shown below:
<apex:page standardcontroller="SVMXC__Site__c" extensions="Location_New_Edit_Controller">
	<apex:form>
		<apex:pageBlock>
			<apex:pageBlockSection>
				<apex:pageBlockSectionItem>
					<apex:outputPanel>
						<div>
							<DSE:DS_DataQuality.... parameters/>
						</div>
					</apex:outputPanel>
				</apex:pageBlockSectionItem>
			</apex:pageBlockSection>
		</apex:pageBlock>
	</apex:form>
</apex:page>

This page works fine in Google Chrome browser. The issue is it doesn't work consistently in IE 11 browser. But, it works in IE 11, only if we do the following:
1. First, load dse.visual.force.com/apex/pageName, then the usual c.visual.force.com/apex/pageName. DSE is the namespace of that Informatica installed package
2. Embed the same VF page in the object's standard page layout & access that record, then load the VF page

The above behaviours suggest that if a VF page uses a managed component, then some additional logic needs to be added to load the related JS libraries. 
Need your suggestions to fix this issue. Thank you!

We were able to overcome this issue by adding *.force.com to the trusted sites of IE browser. Our company IE policy was blocking scripts to run between two different domains: salesforce.com & force.com.
