PhpOffice\PhpSpreadsheet\Worksheet\Drawing() and setRowHeight

[sysgone]

When I try to display a few thousand images from the database, at some point they start to overlap. I noticed that this happens at around 220k pixels in document length
In the loop I set the row height to 100 px and load the images

`
function addImage($path,$coordinates,$sheet){
$drawing = new \PhpOffice\PhpSpreadsheet\Worksheet\Drawing();
$drawing->setPath($path);
$drawing->setCoordinates($coordinates);
$drawing->setWorksheet($sheet);
}

while ($row = $sth->fetch(PDO::FETCH_ASSOC)) {
...
$sheet->getRowDimension(3+$i)->setRowHeight(100,'px');
addImage("thumbs/".$row['picture'].".png", 'G'.(3+$i), $sheet)
...
}
`
The size of the picture does not matter. At some point the pictures start to overlap.
if row height = 100, I can see corectly ~ 1700 records, if I change height to 200px, corect are only ~ half of them
