Proposed solution

// Set some basic options.
$customOptions = [
    'filtersHidden'       => isset($data['options']['filtersHidden'])? $data['options']['filtersHidden'] : $hideActiveFilters,
    'filterButton'        => isset($data['options']['filterButton']) && $data['options']['filterButton'] ? $data['options']['filterButton'] : $showFilterButton,
    'defaultLimit'        => $data['options']['defaultLimit'] ?? Factory::getApplication()->get('list_limit', 20),
    'searchFieldSelector' => '#filter_search',
    'selectorFieldName'   => $selectorFieldName,
    'showSelector'        => $showSelector,
    'orderFieldSelector'  => '#list_fullordering',
    'showNoResults'       => !empty($noResultsText),
    'noResultsText'       => !empty($noResultsText) ? $noResultsText : '',
    'formSelector'        => !empty($data['options']['formSelector']) ? $data['options']['formSelector'] : '#adminForm',
];

// Merge custom options in the options array.
$data['options'] = array_merge($customOptions, $data['options']);

// Add class to hide the active filters if needed.
$filtersActiveClass = $hideActiveFilters && $customOptions['filtersHidden']? '' : ' js-stools-container-filters-visible';

Any update to fix this one? @alikon @Hackwar

@laoneo this one will not be into J 5.1 ?

@georgebara thank you for reporting this. Since you already have a proposal, would you be able to create a pull request for this?
