Hey, I'm not sure if my issue is related in some way to this, but text wrapping behavior seems to have changed from JavaFX 24 to 25.
I have this:

var bottom = new Label(description);
bottom.getStyleClass().add("description");
var vbox = new VBox(top, bottom);

And this piece of CSS:

.description {
    -fx-padding: 0.5em 0 0 0;
    -fx-font-size: 1.083333em;
    -fx-wrap-text: true;
}


After updating to JavaFX 25 the text is truncated. Before it would take as height as needed to show all the text.

Sorry if this is OT, I tried searching for any commit that may have caused this but could not find anything.
The closest thing I found was 7699c44 by @andy-goryachev-oracle but it is also included in v23 and v24. This behavior I'm observing is present only in v25
