I did a quick scan, and the same bug exists in at least `ListView`, which should initialize the VERTICAL PseudoClass in its constructor. Most of the others looked fine, except for the following, which need to be checked more carefully:

I've fixed similar issues with the following pseudoclasses:

ListView:vertical
TableView:unconstrained-resize
TreeTableView:unconstrained-resize
TreeCell:collapsed
TreeTableRow:collapsed
