Nothing displayed if control is used in ListCell/ListView

[Minification]

Here's a "minimal" example of the problem. I pretty much copied your test and simply added a ListView with a custom renderer. Here is the main class:

import javafx.application.Application;
import javafx.collections.FXCollections;
import javafx.collections.ObservableList;
import javafx.scene.Scene;
import javafx.scene.control.ListView;
import javafx.scene.layout.VBox;
import javafx.stage.Stage;

public class JLatexMathFXExample extends Application {

    public static void main(String[] args) {
        JLatexMathFXExample.launch(args);
    }

    @Override
    public void start(Stage primaryStage) throws Exception {
        String latex = "\\begin{array}{l}";
        latex += "\\forall\\varepsilon\\in\\mathbb{R}_+^*\\ \\exists\\eta>0\\ |x-x_0|\\leq\\eta\\Longrightarrow|f(x)-f(x_0)|\\leq\\varepsilon\\\\";
        latex += "\\det\\begin{bmatrix}a_{11}&a_{12}&\\cdots&a_{1n}\\\\a_{21}&\\ddots&&\\vdots\\\\\\vdots&&\\ddots&\\vdots\\\\a_{n1}&\\cdots&\\cdots&a_{nn}\\end{bmatrix}\\overset{\\mathrm{def}}{=}\\sum_{\\sigma\\in\\mathfrak{S}_n}\\varepsilon(\\sigma)\\prod_{k=1}^n a_{k\\sigma(k)}\\\\";
        latex += "\\sideset{_\\alpha^\\beta}{_\\gamma^\\delta}{\\begin{pmatrix}a&b\\\\c&d\\end{pmatrix}}\\\\";
        latex += "\\int_0^\\infty{x^{2n} e^{-a x^2}\\,dx} = \\frac{2n-1}{2a} \\int_0^\\infty{x^{2(n-1)} e^{-a x^2}\\,dx} = \\frac{(2n-1)!!}{2^{n+1}} \\sqrt{\\frac{\\pi}{a^{2n+1}}}\\\\";
        latex += "\\int_a^b{f(x)\\,dx} = (b - a) \\sum\\limits_{n = 1}^\\infty  {\\sum\\limits_{m = 1}^{2^n  - 1} {\\left( { - 1} \\right)^{m + 1} } } 2^{ - n} f(a + m\\left( {b - a} \\right)2^{-n} )\\\\";
        latex += "\\int_{-\\pi}^{\\pi} \\sin(\\alpha x) \\sin^n(\\beta x) dx = \\textstyle{\\left \\{ \\begin{array}{cc} (-1)^{(n+1)/2} (-1)^m \\frac{2 \\pi}{2^n} \\binom{n}{m} & n \\mbox{ odd},\\ \\alpha = \\beta (2m-n) \\\\ 0 & \\mbox{otherwise} \\\\ \\end{array} \\right .}\\\\";
        latex += "L = \\int_a^b \\sqrt{ \\left|\\sum_{i,j=1}^ng_{ij}(\\gamma(t))\\left(\\frac{d}{dt}x^i\\circ\\gamma(t)\\right)\\left(\\frac{d}{dt}x^j\\circ\\gamma(t)\\right)\\right|}\\,dt\\\\";
        latex += "\\begin{array}{rl} s &= \\int_a^b\\left\\|\\frac{d}{dt}\\vec{r}\\,(u(t),v(t))\\right\\|\\,dt \\\\ &= \\int_a^b \\sqrt{u'(t)^2\\,\\vec{r}_u\\cdot\\vec{r}_u + 2u'(t)v'(t)\\, \\vec{r}_u\\cdot\\vec{r}_v+ v'(t)^2\\,\\vec{r}_v\\cdot\\vec{r}_v}\\,\\,\\, dt. \\end{array}\\\\";
        latex += "\\end{array}";

        VBox pane=new VBox();

        ListView<String> lv = new ListView<>();
        lv.setCellFactory(c -> new Celll());

        ObservableList<String> m = FXCollections.observableArrayList();
        m.add(latex);

        lv.setItems(m);

        pane.getChildren().add(lv);

        Scene scene=new Scene(pane);
        primaryStage.setScene(scene);
        primaryStage.setWidth(800);
        primaryStage.setHeight(600);

        primaryStage.show();

    }
}

Here's the Cell renderer:

import com.proudapes.jlatexmathfx.Control.LateXMathControl;
import javafx.scene.control.ListCell;

public class Celll  extends ListCell<String> {

    @Override
    public void updateItem(String item, boolean empty) {
        super.updateItem(item, empty);
        if (item != null) {
            final LateXMathControl l = new LateXMathControl(item);
            setGraphic(l);
        }
    }

}

And here is what is displayed:

I will try to reproduce this, please hold on

sorry for the long delay - I will need to retry on windows, on arch linux it looks ok and I do not use windows for development at the moment.
