[Sketch Bridge] Embedded images with transparent backgrounds get incorrectly cropped/moved

See the attached project. It contains an embedded PNG image of a blue circle (150x150) at the center of a transparent rectangle (300x200). The image is the same size as the Artboard.

• When the circle is exported as "Merged", the result is as expected.
• When the circle is exported as "Child", Qt Bridge crops away the transparent parts of the embedded image, effectively moving the circle.
