How to refresh the EditorTextField ui

This is my code

    @Override
    public void createToolWindowContent(@NotNull Project project, @NotNull com.intellij.openapi.wm.ToolWindow toolWindow) {
        EditorTextField requestUrlTextField = new EditorTextField();
        requestUrlTextField.setOpaque(false);
        MessageBusConnection busConnection = ApplicationManager.getApplication().getMessageBus().connect();
        busConnection.subscribe(EditorColorsManager.TOPIC, new EditorColorsListener() {
            @Override
            public void globalSchemeChange(EditorColorsScheme scheme) {
                SwingUtilities.invokeLater(new Runnable() {
                    @Override
                    public void run() {
                        requestUrlTextField.repaint();
                        requestUrlTextField.revalidate();
                    }
                });
            }
        });
        JPanel jPanel = new JPanel(new BorderLayout());
 
        jPanel.add(requestUrlTextField);
        JPanel root = new JPanel(new BorderLayout());
        root.add(jPanel, BorderLayout.NORTH);

        toolWindow.getContentManager().addContent(
                toolWindow.getContentManager().getFactory().createContent(root, "", false)
        );
    }

When I switched themes, it became smaller and had no inner margins

But when I closed tool windows and reopened it, it returned to its original state
