does windows 10 use wininet.dll or default browser engine for non-browser https requests

Does windows 10 use %windir%\system32\wininet.dll or default browser engine for non-browser https requests and response processing?

I ask because if/when my edge dev channel install, configured as my default browser, is experiencing some regression that causes it to intermittently crash or load from scratch very slowly subjectively it seems to affect performance of other non-browser app aspects of my windows 10 shell experience.
