I'm trying to get Chrome Logger working in an Angular app running against a PHP backend, but for some reason the X-ChromeLogger-Data header doesn't seem to be coming through when the API is accessed by the Angular app.
If I open the API's access point directly or hit it with a jQuery.get() request everything works fine, even if I make the ajax request from another domain. The API also works correctly otherwise, even when used by the Angular app. It's just that one header disappears somewhere along the way. It doesn't even appear in Chrome's console.
What could cause a header to disappear?
Here's a request made with jQuery.get()
Request:

And here's one from the Angular app:

The Angular code used to make the above request:
$http.get( endpoint, { params : { action : 'load' } } ).then(
function( response ) {
console.log( response );
},
function() {
console.log( 'fail' );
}
);
