This does not seem like it will apply the custom headers to a subframe or child window navigated to about:blank or a blob URL (*) page or sub-resources loaded from them. Notice that about:blank inherits the security origin of its parent/opener frame.

(*) with the same origin as the document that has custom headers

I added a test verifying that this case behaves correctly.
