[ITensorMakie] [BUG] Unable to use ITensorGLMakie at all

[AmdaU]

Description of bug

I tried to get the ITensorGLMakie backend to work in various situations but to no avail.

Minimal runnable code

using ITensors
using ITensorGLMakie

i = Index(2, "index_i")
j = Index(10, "index_j")
k = Index(40, "index_k")
l = Index(40, "index_l")
m = Index(40, "index_m")
A = randomITensor(i, j, l)
B = randomITensor(i, j, l, m)
C = randomITensor(k, m)

ABC = @visualize A * B * C

observed behavior
I would expect a window to appear with the visualization. The visualization works when using ITensorUnicodePlots instead.

[mtfishman]

Thanks, we're aware if this issue: MakieOrg/GraphMakie.jl#142. It was fixed in MakieOrg/Makie.jl#3284 which will be made available when a new version of Makie is released.

[mtfishman]

For the time being it should work if you use Makie v0.19.10.
