Why are my manually-edited face coordinates not applied?

Cloudinary enables you to manually edit your image's face coordinates. This can be done by either sending custom face_coordinates via the API (upon upload or using the explicit method for example), or setting them via the Media Library using the "Define Area of Interest" functionality:

Using a_ignore (to prevent auto-orientation) resets the face information, including the manually-edited face coordinates. Therefore, when used together with the g_face transformation, a_ignore can cause unexpected behavior.

For example, consider the following image which is set with manually-edited coordinates:

However, when using a_ignore along with the g_face transformation, the result is an incorrectly cropped image:

In order to avoid the face information reset, you can chain the a_ignore parameter, so it is within a different transformation component, as follows:
