VirtualizedScrollPane with StyleClassedTextArea does not scroll to bottom with dragging scrollbar

[r-sop]

Expected Behavior

Dragging the Scrollbar to the bottom scrolls the text inside the StyleClassedTextArea to the last line.

Actual Behavior

This works when using the mouse wheel:

But not when dragging the scrollbar:

Thanks for reporting, can you please provide demo code as I haven't been able to reproduce my side.

[r-sop]

Thanks for the fast reply.

Will try. In a first attempt with a minimal exmaple (without css) I also cannot reproduce it..

[r-sop]

Finaly had time to reproduce it with a minimal example:

<?xml version="1.0" encoding="UTF-8"?>

<?import org.fxmisc.flowless.VirtualizedScrollPane?>
<?import org.fxmisc.richtext.StyleClassedTextArea?>
<?import javafx.scene.layout.BorderPane?>
<BorderPane xmlns="http://javafx.com/javafx/" xmlns:fx="http://javafx.com/fxml" fx:controller="com.example.demo.HelloController">
    <center>
        <VirtualizedScrollPane>
            <content>
                <StyleClassedTextArea fx:id="area" style="-fx-padding: 0.5em;"/>
            </content>
        </VirtualizedScrollPane>
    </center>
</BorderPane>

So the padding seems to be the problem.

@r-sop Thanks for the test case, have submitted a PR to Flowless to fix.
