Steps to reproduce the behavior

• Create a view with a DataTable component in it;
• Add a Column component in it and set its selection-mode attribute to "multiple";
• Use the columns headercheckboxicon slot to replace the "select all" checkbox icon;
• Use the columns rowcheckboxicon slot to replace rows checkbox icon;
• Add a Column for any other field you need (though this is not the point);

Though the rowcheckboxicon seems to work as expected, the "select all" checkbox fallback icon isn't being replaced with headercheckboxicon slot's content.

Expected behavior

Content passed through the headercheckboxicon slot should replace checkbox fallback icon.
