Cannot output Windowed fields with together with standard fields

[simone-silvestri]

MWE

grid = RectilinearGrid(size = (5, 5, 5), extent = (1, 1, 1))
model = HydrostaticFreeSurfaceModel(; grid)
c = CenterField(grid; indices = (:, :, grid.Nz))
d = CenterField(grid)
JLD2OutputWriter(model, (; c, d), filename = "test", schedule = IterationInterval(1))

fails with

julia> JLD2OutputWriter(model, (; c, d), filename = "test", schedule = IterationInterval(1))
ERROR: ArgumentError: view indices (1:5, 1:5, 1:5) do not intersect field indices (Colon(), Colon(), 5:5)

It looks like there are problems also if trying to save the windowed field by itself

julia> JLD2OutputWriter(model, (; c), filename = "test1", schedule = IterationInterval(1))

However, by specifying the indices it works

julia> JLD2OutputWriter(model, (; c), filename = "test1", schedule = IterationInterval(1), indices = (:, :, grid.Nz))
JLD2OutputWriter scheduled on IterationInterval(1):
