 Any plugin that modifies image paths through the `image_downsize` and
 `the_content` filters prevents `get_the_post_format_image()` from properly
 removing the first parsed image from the content later passed to
 `get_the_remaining_content()`.

 When `get_the_post_format_image()` parses post content to extract an
 image, the content is accessed directly from the `$post` global without
 applying the `the_content` filter. In the case of a user with a CDN plugin
 such as Jetpack Photon enabled, this causes the string replacement meant
 to strip out the first image to fail because the image path returned by
 `wp_get_attachment_image_src()` is modified through the `image_downsize`
 filter. Since the corresponding filter hooked to `the_content` hasn't
 modified the content the string replacement is applied to, the parsed
 image isn't removed from the content.
