Text Area's node orientation doesn't reflect on text when updated from an accelerator.

KeyCombination rtlShortcut = new KeyCodeCombination(KeyCode.R, KeyCombination.CONTROL_ANY);
        Runnable RTLrunnable = () -> {
            Platform.runLater(() -> {
                optionTA.setNodeOrientation(NodeOrientation.RIGHT_TO_LEFT);
            });
            System.out.println("optionTA's node orientation: " + optionTA.getNodeOrientation());
        };

        KeyboardShortcuts.getInstance().addKeyboardShortcut(rtlShortcut,RTLrunnable);

The print statement shows the optionTA's node orientation does change, but the text doesn't reflect so. When I use a choice box that's next to the text area, it does change:

        textDirectionCB.getItems().addAll(NodeOrientation.LEFT_TO_RIGHT, NodeOrientation.RIGHT_TO_LEFT);
        
onOrientationChanged(optionTA::setNodeOrientation);

private void onOrientationChanged(Consumer<NodeOrientation> orientationChangeFunc) {
        textDirectionCB.getSelectionModel().selectedItemProperty()
                .addListener((a, b, selectedOrientation) ->
                        orientationChangeFunc.accept(selectedOrientation));
    }

Whether I make sure the code is run from the UI thread or not by calling Platform.runLater(...), nothing changes.

okay, I realized since the FXML's file/controller class are duplicated on the UI, one got the shortcut and the other's didn't (because the accelerators are a map. As a workaround, I should only activate the shortcut while the text area has focus.
P.S: I would've deleted the issue, but apparently this is not possible on this repo, so marking it as closed.
