Filter with default filter

Hi,
I found an issue in filters. If I have date filter on column and it has default filter value. The problem appears if I clear filter input manually to empty string "". Datagrid does not set default filter in this case and also hides the reset button. So I am not able to reset grid to default filter. Here is the code. I am using it with Nextras ORM.

$grid->addColumnDateTime('closed', "$cDomain.date")
    ->setRenderer( function ( $item ) use ( $cDomain ) {
        /** @var Task $item */
        $title = $this->translator->translate("$cDomain.$item->state");
        return '<span title="' . $title . '">' . $item->closed->format( 'j. n. Y' ) .  '</span>';
    })
    ->setTemplateEscaping( FALSE )
    ->setSortable()
    ->setFilterDate()
        ->setCondition( function ($fluent, $value) {
            Debugger::log($value);
            /** @var \Nextras\Orm\Mapper\Dbal\DbalCollection $fluent */
            $start = DateTime::createFromFormat( 'j. n. Y', $value)->setTime( 0, 0, 0 );
            $end = DateTime::createFromFormat( 'j. n. Y', $value)->setTime( 23, 59, 59 );
            $fluent->getQueryBuilder()
                ->from('tasks', 'tasks')
                ->andWhere( 'tasks.closed > %dt', $start )
                ->andWhere( 'tasks.closed < %dt', $end );
        });

$defaultDate = (new DateTime())->modify('- 14 Day');
$grid->setDefaultFilter(['closed' => $defaultDate->format( 'j. n. Y' )]);

It is not fatal but it has to be fixed via session.

Start by reproducing the issue with addColumnDateTime(), setFilterDate(), and setDefaultFilter() using the example in the report, then trace the behavior when the date input is cleared. Done means clearing the input does not lose the default filter and the reset button remains available so the grid can return to its default state.
