Coarse arc segmentation with circular layout

[alephreish]

Arcs representing orthogonal components of the branches in the circular layout look very coarsely segmented with some trees. The effect is obviously particularly pronounced closer to the root:

library(ggtree)
# ggtree v3.8.2

set.seed(100)
tree <- rtree(100)
ggtree(tree, layout = "circular")

Most of the arcs are drawn with two straight segments.
