Differentiating across `add_edges` causes Zygote to segfault

Using the add_edges function on a path that is differentiated with Zygote.jl causes a segfault and kills the julia process. The version is v1.1.0
Could be related to https://github.com/FluxML/Zygote.jl/issues/1580

using GraphNeuralNetworks
using Zygote

s = [1, 2]
t = [2, 3]
w = Float32[0.5, 0.7]

g = GNNGraph((s, t, w))

function loss_fn(wnew)
    # fixed new edges, only weights are differentiable
    snew = [1, 2]
    tnew = [2, 3]

    g2 = add_edges(g, (snew, tnew, wnew))

    return sum(get_edge_weight(g2))
end

wnew = Float32[0.1, 0.2]

gradient(loss_fn, wnew)

The resulting segfault is

[205339] signal 11 (1): Segmentation fault

Reproduce the crash with the Julia and Zygote example in the issue, then inspect add_edges at GNNGraphs/src/transform.jl:326, where the stack trace enters. Compare the behavior with the related Zygote issue. Done means differentiating loss_fn returns a gradient without segfaulting or killing the Julia process.
