TooltipCellDecorator does not hide after clicking the decorated button that refreshes list

[komasoftware]

This code :

        ButtonCell buttonCell = new ButtonCell(IconType.STAR, ButtonType.INFO, ButtonSize.SMALL);
        final TooltipCellDecorator<String> decorator = new TooltipCellDecorator<String>(buttonCell);
        decorator.setText("als favoriet markeren");
        Column<Template, String> buttonCol = new Column<Template, String>(decorator) {
            @Override
            public String getValue(Template object) {
                return "";
            }
        };
        buttonCol.setFieldUpdater(new FieldUpdater<Template, String>() {

            @Override
            public void update(int index, Template template, String value) {
                template.setFavorite(Boolean.TRUE);
                activity.saveTemplate(template);
            }
        });

When clicking the button, my activity is called which will trigger a refresh of the backing list of the datagrid. the tooltip does not notice this but you can no longer 'mouseout' of the previously rendered button.

I could not easily find a way to hide the tooltip in the FieldUpdater myself either...
