SecureWindow instance does not support opening blob files?

[SourabhMulay]

I'm encountering an error that states: "SecureWindow.open supports http:, https:, mailto: schemes, and relative URLs."

I attempted to create a Blob instance with the type "octet-stream" and open it using window.open(URI), but this resulted in the aforementioned error. I suspect that the restrictions imposed by Lightning Locker and strict Content Security Policies (CSP) are preventing the use of Blobs. Is there any way to disable the Locker Service without compromising the code API versions?

In current repo which code contribute functionality of lightning locker? Just wanted to know more about it!!
