Describe the bug

Let's assume we have a Grid instance with: grid.setRowsDraggable(true) All columns of the grid are then - as expected - draggable.

Now hide a column by invoking: grid.getColumnByKey("myColumn").setVisible(false); The column is now hidden - ok.

Now make the column visible again: grid.getColumnByKey("myColumn").setVisible(true);

The column is now visible again - but it is not draggable anymore. The HTML attribute draggable="true" of the related vaadin-grid-cell-content tag is gone.

This was not an issue with Vaadin 20.0.6

Note: with grid.getColumnByKey("myColumn").setVisible(true); UI.getCurrent().push(); grid.setRowsDraggable(true); grid.getDataProvider().refreshAll() it is working. But I guess this is not the way it is intended.

Expected-behavior

After invoking setVisible(false) and later setVisible(true) on a draggable grid column the column should still be draggable

Reproduction

build up a grid with at least one column and make the rows draggable with grid.setRowsDraggable(true);

Now use something to toggle the visibility of a column of this grid, e.g. a simple button: Button button = new Button(); AtomicBoolean isVisible = new AtomicBoolean(true); button.addClickListener(cel -> { grid.getColumnByKey("myDraggableColumn").setVisible(isVisible.get()); isVisible.set(!isVisible.get()); });
