Makie: Linked camera of 3d plots go out of sync on slider change

I have a figure with two LScenes and a slider which is used to change data in the scenes. I have linked the cameras in the two LScenes, using the method shown in this post. The problem is that when I change the slider one of the camera gets reset. Here is the MWE,

using GLMakie

npts = 100
n = 10
pts_1_series = [rand(Point3f, npts) for _ in 1:n]
pts_2_series = [rand(Point3f, npts) for _ in 1:n]

fig = Figure()
l1 = LScene(fig[1,1], scenekw=(;center=false))
l2 = LScene(fig[1,2], scenekw=(;center=false))

sg = SliderGrid(fig[2,:][1,1], (label="n", range=1:n, startvalue=1), width=350, tellwidth=false)

pts_1 = @lift pts_1_series[$(sg.sliders[1].value)]
pts_2 = @lift pts_2_series[$(sg.sliders[1].value)]

scatter!(l1, pts_1)
scatter!(l2, pts_2)

link_cameras_lscene(f; step=0.01) = begin
    scenes = filter(x -> x isa LScene, f.content)
    cameras = map(x -> cameracontrols(x.scene), scenes)

    for i ∈ 1:length(cameras)
        on(cameras[i].eyeposition) do eye
            for j ∈ 1:length(cameras)
                i == j && continue
                if sum(abs, eye - cameras[j].eyeposition[]) > step
                    update_cam!(scenes[j].scene, cameras[i])
                end
            end
        end
    end
    f
end

fig = link_cameras_lscene(fig; step=0.1)

Any idea how I can stop the cameras from updating on slider change?

I’ve trying to understand why this happens. I think it happens because after the slider change, update_state_before_display!(f::FigureAxisPlot) is called somewhere, which calls reset_limits!(ax) on all its scenes.

Does anyone know how I can prevent this “update” from happening on slider change?
