autosize() on Node may be what you want (sizes it then afterward you can read
values)?

I was thinking that certain nodes (e.g., TextField) won’t provide a valid pref
size until the window was made visible (and the CSS had been evaluated).
A few times I’ve added code set Window Opacity to zero, do a Window show/hide,
then reset Window Opacity to one. Then you should get valid pref
If you are interested in the preferred height, prefHeight(-1) should
get you what you want. If this is before the first layout pass takes
place, you will also want to call applyCss() before prefHeight(-1).
Note: prefHeight(-1) is what autosize() calls internally, but it does
not call applyCss().
