random collapse of partial internal node

[dengzq1234]

As I observe, ete4 collapse branchs or nodes based on the collpase level(defautl is 10), which usually collapse the internal nodes. But here I find some sitaution that ete4 collapse partial children of internal nodes which cause lack of information of collapsed clade

As the picture above, the big grey triangle is the default collapse clade but is only half of the children leaves of the internal node which make the collapsed clade meanless
