Bugfix: Make sure title of actionbutton in displayed on hover over

[eynimeni]

When actionbutton is added to a table like:

    $data[] = [
        'label' => '', // Name of your action button.
        'href' => '#', // You can either use the link, or JS, or both.
        'iclass' => $values->isactive ?? '0' == '1' ? 'fa fa-eye' : 'fa fa-eye-slash', // Add an icon before the label.
        'arialabel' => 'eye', // Add an aria-label string to your icon.
        'title' => $values->isactive ?? '0' == '1' ? get_string('deactivate', 'local_taskflow') : get_string('activate', 'local_taskflow'), // We be displayed when hovered over icon.
        'id' => $values->id . '-'  . $this->uniqueid,
        'name' => $this->uniqueid . '-' . $values->id,
        'methodname' => 'toggleitem', // The method needs to be added to your child of wunderbyte_table class.
        'nomodal' => true,
        'data' => [ // Will be added eg as data-id = $values->id, so values can be transmitted to the method above.
            'id' => $values->id,
        ],
    ];
    table::transform_actionbuttons_array($data);

hover over display of title is currently not working, should be fixed
