Steps to reproduce the issue

Add the code:
echo JHTML::_('calendar', '', 'name', 'id', '%d %B %Y %H:%M', array('size' => '20', 'showTime' => true));
at the beginning of the file administrator/components/com_content/tmpl/article/edit.php just after the line:
defined('_JEXEC') or die;
Then, create a new Joomla article

Expected result

A calendar field should appear at the top of the view (that's the code we used until now to display the calendar form in our component):

Actual result

The calendar field doesn't display the calendar when clicking on the button and a notice message appear:

"Notice : Undefined variable: dataAttribute in \layouts\joomla\form\field\calendar.php on line 117"

System information (as much as possible)

Clean Joomla 4 beta 1

Additional comments

Adding the line:
'dataAttribute' => '',
after the line:
'maxYear' => $maxYear,
in the file libraries/src/HTML/HTMLHelper.php fixes the problem but maybe there is a better way to fix it ? Or maybe another method should be used to load the calendar ?
