GPX export of image new position use old coordinates

[StephaneP]

What steps will reproduce the problem?

1. Load some images (https://josm.openstreetmap.de/attachment/ticket/21330/bug_support_layer_A.zip)
2. Export a gpx from these images, and load it in Josm
3. Open the Correlate image with gpx window, and create a support layer from the previous exported Gpx
4. Enable "override position", move some images, and validate the correlation.
5. Export a gpx from the image positions then load it in Josm

What is the expected result?

The new exported Gpx point should be the same as the images.

What happens instead?

The exported Gpx file use the old images coordinates.

Please provide any additional information below. Attach a screenshot if possible.

On this screenshot, image with new coordinates, and the exported gpx.

The same process without the support layer, but with manual image (photo adjust plugin) position modification is working correctly.
