DataGrid with ItemDetailsRenderer in a Fragment has gaps for the first three rows

Support
#1

When using the ItemDetailsRenderer in a DataGrid which is in a fragment, it seems there is always a larger gap for the first three rows. I have seen this in several datagrids so far:

After clicking it once and closing it again, the gap is gone.

Code within a fragment:
datagrid.setItemDetailsRenderer(createSqlDetailsRenderer());

    protected ComponentRenderer<JmixTextArea, MyDTO> createSqlDetailsRenderer() {
        return new ComponentRenderer<>(
                () -> createSqlDetailsRendererComponent(),
                (jmixTextArea, myDto) -> { jmixTextArea.setValue(myDto.getValue()); }
        );
    }

    protected JmixTextArea createSqlDetailsRendererComponent() {
        JmixTextArea sqlField = uiComponents.create(JmixTextArea.class);
        sqlField.setId("sqlField");
        sqlField.setHeight("12em");
        sqlField.setWidthFull();
        sqlField.setReadOnly(true);
        return sqlField;
    }
