Alignment of required-field-indicator in GridLayout

I updated from 7.3.2 to 7.6.5.
It seems that the alignment of the required-field-indicator changes significant in GridLayouts.
In 7.3.2 the field-indicator was just on the right of a TextField.
In 7.6.5 the field-indicator is aligned to the right of the grid column. If the column is much wider than the TextField and the TextField is aligned to the left, there is a lot of space between the field and the indicator, which does not look really good.

I have reproduced it with this little code, which i adapted from the vaadin demo:

public class GridTest extends GridLayout
{
    GridTest sample;
    
    public GridTest()
    {
        super();
        // Create a grid layout
        sample = this;
        sample.addStyleName("outlined");
        sample.setWidth(600, Unit.PIXELS);
        sample.setHeight(300, Unit.PIXELS);
    
        generateMatrixGrid(3, 2);
    }

    private void generateMatrixGrid(final int rows, final int columns) {
        sample.removeAllComponents();
        sample.setRows(rows);
        sample.setColumns(columns);
    
        for (int row = 0; row < sample.getRows(); row++) {
            for (int col = 0; col < sample.getColumns(); col++) {
                final LayoutChildComponent child = new LayoutChildComponent(sample, false);
                sample.addComponent(child);
                sample.setRowExpandRatio(row, 0.0f);
                sample.setColumnExpandRatio(col, 0.0f);
            }
        }
    }
    
    class LayoutChildComponent extends TextField
    {
        public LayoutChildComponent(GridLayout grid, boolean bool) {
            setValue("Child " + (grid.getComponentCount() + 1));
            setRequired(true);
        }
    }
}

Is this a bug?

the problem exists with the reindeer theme. The required-field-indicator is aligned correct with valo.
