Done. Can confirm it fixes the downstream issue KristofferC/PGFPlotsX.jl#325

Now we just need to run the tests with debugging enabled to fix CI

Hmm... I thought the difference between the type trees in 1.6 and 1.10 came from the circles in the nodes, but doesn't seem to be the case.
But this accidentally fixes #188 I guess

For reference:

1.10.2

1.6.5

🤦🏻 , so julia 1.6. added a new type... ?
