Description
I have a SpatialData with two images, a and b. Each image is mapped to two coordinate system: global and aligned, with the following mapping:
a -> global: identity
b -> global: identity
a -> aligned: identity
b -> aligned: affine
in the viewer, when I open the aligned images, things look good, but if I rightclick image b and use Split Stack to separate out the channels, then my aligned coordinated system seems to be ignored, and the channels all get reset to global. Mean (or other) projections don't seem to have this issue.

Research direction
Start by reproducing the issue in the viewer with two images mapped to global and aligned, then use the Split Stack action on image b. Trace why the resulting channels use global instead of retaining the aligned coordinate system, and verify that splitting preserves the displayed alignment, as mean projections already appear to do.
