Wrong dimensions after reduce_cube_spatial in dry run

[soxofaan]

problem isolated from problem in large process graph in eu-cdse/openeo-cdse-infra#509:

• target : cube with dimensions x, y, t and bands
• data: cube with dimensions x, y and t (e.g. after reduce_dimension along bands dimension)
• resampled = data.resample_cube_spatial(target)
• resampled.add_dimension("bands")

This used to work, but started failing with OpenEOApiException: A dimension with name bands already exists.

[soxofaan]

bug was introduced by Open-EO/openeo-python-client#690:

resampled = data.resample_cube_spatial(target)

resampled adapted full set of dimensions from target, including "bands", resulting in dimension set

x, y, t and bands

while only the spatial dimensions should be updated, and other dimensions should be preserved:

just x, y and t

[soxofaan]

should be fixed with e90316d

just verified that a job from https://github.com/eu-cdse/openeo-cdse-infra/issues/509 (based on j-250424120917488197b069e5129b0b9e) now works on CDSE staging (while it fails with DimensionExists: A dimension with name bands already exists on CDSE prod)
