Apologies for delay on this review, Change looks good but I did observe an issue with layout of TabPane header area when the header is set to be shown on Left or Right side. The last tab-header's border seems to be clipped.
Please check the code below. This is a very specific scenario, If tab's label is changed from "Tab" to "tab" then the issue does not occur. I did not observe any other such scenarios yet.

import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.TabPane;
import javafx.scene.control.Tab;
import javafx.stage.Stage;
import javafx.geometry.Side;

public class TabPaneExample extends Application {
    public static void main(String[] args) {

    public void start(Stage primaryStage) {
        Tab tab0 = new Tab("Tab 0");
        Tab tab1 = new Tab("Tab 1");
	Tab tab2 = new Tab("Tab 2");
	TabPane tabPane = new TabPane();
        tabPane.getTabs().addAll(tab0, tab1, tab2);

        Scene scene = new Scene(tabPane);
![with fix](https://user-images.githubusercontent.com/11330676/103559181-bd8ef880-4edb-11eb-8b87-cc6b0045b366.png)    |   ![without fix](https://user-images.githubusercontent.com/11330676/103559271-deefe480-4edb-11eb-99eb-fbc354d070fe.png)
Output with this fix.      |    Output without this fix.

Edit: Also, please note the difference of space between letter `a` and `b` in Tab's label.
