Variational smoother was seen to tangle an element in a mixed quad-tri mesh #4543

Description

@GiudGiud

Using the code in this PR:
idaholab/moose#33522

we can get a starting mesh that when smoothed gains an inverted element.
see the MWE input in MOOSE

We're thinking the quadrature points being in the volume away from the nodes is the issue.
I'll investigate GL quadrature to remedy that
