Chrome has EMET disabled because it’s own memory protections conflict and it just won’t execute.
When you’re make a web view for Windows you’re either bringing a long your own rendering or using Edge because it’s included.
No one wants to secure their own rendering which is why they all use whatever is already there which is EMET which is a pita to test so they just go with Edge.
native is just jargon for “what is already there.”
