viewClade behaving oddly since update to ggtree_1.12.6

[matbeale]

Hi,
I've just updated to the latest version of R and ggtree, and viewClade has stopped working (presumably something to do with scaling). In the example below, the tree basically rescales to a single branch. I've never noticed this behaviour before, and I'm using trees I've plotted before with the same code. Please see my example:

nwk <- system.file("extdata", "sample.nwk", package="treeio")
tree <- read.tree(nwk)
ggtree(tree) + geom_text2(aes(subset=!isTip, label=node), hjust=-.3)
