Oh wow. Well you really need "pva all the way down". Meaning the pva needs to have a continuous path to the glass bed. Because PVA barely sticks at all to PLA.
So the "horizontal expansion" fixes this for some part shapes, but not for this one.
I'm hoping some future version of Cura will be able to do "PVA all the way down" automatically.

I have tried "ooze shield" for PLA+PVA : it does not work at all. It's better without anything.
I have tried a new tower of 25x25mm and 4mm thickness :
As you can see, I have PVA residues on the part. The PVA is red Formfutura Atlas support but I have the same behaviour with Ultimaker PVA.
