How to display an ActionToolbar in a table cell ?

So I have code like this that works properly in almost every place I know off

AnAction source = ActionManager.getInstance().getAction("my_group");
source.getTemplatePresentation().putClientProperty(ActionButton.HIDE_DROPDOWN_ICON, Boolean.TRUE);

DefaultActionGroup actionGroup = new DefaultActionGroup(source);
ActionToolbar t = ActionManager.getInstance().createActionToolbar(
        "My_PLACE",
        actionGroup,
        true);
t.getComponent().setOpaque(false);
t.getComponent().setBorder(JBUI.Borders.empty());

JPanel jPanel = new JPanel(new BorderLayout());
jPanel.add(t.getComponent(), BorderLayout.NORTH);

add(jPanel, BorderLayout.SOUTH); // <----

However if I want to display this toolbar in a cell of `JBTable`, it doesn't work. I've tried multiple things, wrapping in a `JPanel`, setting minimum size, etc. The component don't show up.

class HyperlinkTableCellRenderer implements TableCellRenderer {
    @Override
    public Component getTableCellRendererComponent(JTable table, Object value, boolean selected, boolean focus, int row, int column) {
        AnAction source = ActionManager.getInstance().getAction("my_group");
        source.getTemplatePresentation().putClientProperty(ActionButton.HIDE_DROPDOWN_ICON, Boolean.TRUE);

        DefaultActionGroup actionGroup = new DefaultActionGroup(source);
        ActionToolbar t = ActionManager.getInstance().createActionToolbar(
                "MY_PLACE",
                actionGroup,
                true);
        t.getComponent().setOpaque(false);
        t.getComponent().setBackground(RenderingUtil.getBackground(table, selected));
        t.getComponent().setBorder(JBUI.Borders.empty());


//        t.getComponent().setMinimumSize(t.getComponent().getPreferredSize());
//        t.getComponent().setVisible(true);
//        Dimension preferredSize = t.getPreferredSize();
//        t.setMinimumButtonSize(new Dimension(16, 16));
//        t.setLayoutPolicy(ActionToolbar.NOWRAP_LAYOUT_POLICY);


        JPanel holder = new JPanel(new BorderLayout());
        holder.add(t.getComponent());

        return holder;
    }
}

I am not as well versed in swing code and behavior as I would be, so I am not sure where to start to debug.

I noticed this on 2021.3, but it's likely present on older versions.

Thank you in advance for any advice.
