Grid DetailRow breaks Layout

Hello.

Given a HorizonalLayout with:
Label | Grid | Button

The Grid has 2 rows and DetailRows set and the Button hides/shows the Label.

If the DetailRow of the first row visible and I click the Button to hide the Label, the Grid disappears.
This does not happen if only the DetailRow of the second row is visible or none DetailRow is visible.

EDIT: this happens in 7.5.0 and 7.5.1
In 7.5.2 and 7.5.3 the Grid makes all detailRows invisible before the Label will be hidden.
Thus the Grid doesn't dissapear anymore.

Sample Code

HorizontalLayout hl = new HorizontalLayout();
        hl.setSizeFull();
        final Label leftLabel = new Label("leftLabel");
        leftLabel.setSizeUndefined();

        final Grid grid = new Grid();
        Column col_a = grid.addColumn("a");
        col_a.setMaximumWidth(100);
        grid.addColumn("b");

        grid.setSizeFull();
        grid.setDetailsGenerator(new DetailsGenerator() {

            @Override
            public Component getDetails(final RowReference rowReference) {
                return new Label(rowReference.getItem().toString());
            }
        });

        grid.addItemClickListener(new ItemClickListener() {

            @Override
            public void itemClick(final ItemClickEvent event) {
                grid.setDetailsVisible(event.getItemId(), !grid.isDetailsVisible(event.getItemId()));
            }
        });

        grid.addRow("a1", "b1");
        grid.addRow("a2", "b2");

        Button hideButton = new Button("hide/show leftLabel");
        hideButton.addClickListener(new ClickListener() {

            @Override
            public void buttonClick(final ClickEvent event) {
                leftLabel.setVisible(!leftLabel.isVisible());
            }
        });

        hl.addComponent(leftLabel);
        hl.addComponent(grid);
        hl.addComponent(hideButton);
        hl.setExpandRatio(grid, 1);
        setContent(hl);
