addDecorator with tooltip not working on grids with addTotals line

[mkrecek234]

Steps to reproduce:

1. Setup any grid or crud to have a decorator and also the table to have addTotals line:

   public function setModel(Model $model, $fields = null): void
   {    
   
       parent::setModel($model);
   
       $this->addDecorator('account', new  \Atk4\Ui\Table\Column\Tooltip(
           [
               'tooltip_field' => 'account_description',
               'icon' => 'info circle blue',
           ]));
       $grid->table->addTotals(['booked_date' => 'Balance', 'value' => ['sum']]);
    ...}

2. If you keep the addTotals line it will throw an error:

   Critical Error
   Error: Call to a member function getTag() on array

   If you delete the addTotals line, it will work.

I can reproduce with this code:

// https://github.com/atk4/ui/issues/1799
$table->addDecorator('salary', new \Atk4\Ui\Table\Column\Tooltip([
    'tooltip_field' => 'name',
    'icon' => 'info circle blue',
]));

on demos/collection/table.php

but I get slightly different exception:

Error: Call to a member function getTotalsCellHtml() on array

but the line is covered https://app.codecov.io/gh/atk4/ui/blob/develop/src/Table.php, so some unexpected data structure is passed
