Edge Bug related to Enterprise Site List

I have been rolling out Edge throughout our company for the last 2 months with the vision that we could consolidate to one browser and forgo browsers like IE and Chrome. However, some of our sites are still running features in SharePoint 2010 that only work in IE. We are actively moving everything to Sharepoint 2016 but I fear that may not be enough. I will lay this out in a Need Action Result Format to help identify the problem.
 
Need: We wanted to make sure that on our SharePoint site we ran the URL in Compatability mode so that we could keep functions where a file opens up in InfoPath. 
Action: We added the specific root URL to the Enterprise site list and set it to open in IE 11, redirect mode false, standalone browser false, and compat mode default. In times past this has allowed older sites to operate in edge.
Results: This does indeed bring the site to operate semi-close to how it was in IE but it could still not recognize infopath. This put me back to the drawing board
 
Action: We added the specific root URL to the Enterprise site list and set it to open in IE 11, redirect mode true, standalone browser true, and compat mode default. 
Result: This is a less elegant solution as it opens up a completely new tab however it restored the rest of the functionality needed where documents opened up in infopath based on a link. 
 
Bug: There was one caveat to the solution. When someone received a link that navigates in that root URL in an email from outside the browser it would not open up the link in compatibility mode thus circumventing that policy we had set.
