Many thanks for developing and maintaining such a useful package! When I try to plot pie charts on top of the nodes of a dendrogram, only one chart is shown. Something similar also happens when I use scale_x_reverse() or scale_y_reverse(), but with coord_flip() I get the expected result.

MRE:

# create a random tree with 5 nodes
library(ggtree)
set.seed(1)
tree <- rtree(3)

# create a pie chart for each node
data <- data.frame(node = 1:5, a = sample(1:100, 5), b = sample(1:100, 5))
pies <- nodepie(data, cols = c("a", "b"))

# Should show a the tree with 5 pie charts, but only one chart is displayed. 
# Works as expected if layout_dendrogram() is removed
ggtree(tree) + layout_dendrogram() + geom_inset(pies)

Result:

Any advice on how to deal with this would be great!
