Column menus are a great feature of Tabulator and according to the documentation it should be possible to add it to *any* column. Unfortunately I'm not able to add one to the header of a column group. Am I doing it wrong or is this not (yet) supported? The code snippet below demonstrates the behaviour. All columns except Group1 get a menu.

If it is not supported I tend to use the solution from [Tabulator - Add menu button to column header](https://stackoverflow.com/questions/53301995/tabulator-add-menu-button-to-column-header) but there I cannot see a way to identify the column component to which the menu would belong when the formatter is executed which would be necessary as I would need to create menu items in dynamically created Tabulators and columns depending on the data of the column.

Any suggestions?
