Images rotated when added to PDF in itext7

I'm using the following extension method I built on top of itext7's com.itextpdf.layout.Document type to apply images to PDF documents in my application:

fun Document.writeImage(imageStream: InputStream, page: Int, x: Float, y: Float, width: Float, height: Float) {

    val imageData = ImageDataFactory.create(imageStream.readBytes())
    val image = Image(imageData)
    val pageHeight = pdfDocument.getPage(page).pageSize.height

    image.scaleAbsolute(width, height)

    val lowerLeftX = x
    val lowerLeftY = pageHeight - y - image.imageScaledHeight

    image.setFixedPosition(page, lowerLeftX, lowerLeftY)

    add(image)
}

Overall, this works -- but with one exception! I've encountered a subset of documents where the images are placed as if the document origin is rotated 90 degrees. Even though the content of the document is presented properly oriented underneath.

Here is a redacted copy of one of the PDFs I'm experiencing this issue with. I'm wondering if anyone would be able to tell me why itext7 is having difficulties writing to this document, and what I can do to fix it -- or alternatively, if it's a potential bug in the higher level functionality of com.itextpdf.layout in itext7?

Some Additional Notes

• I'm aware that drawing on a PDF works via a series of instructions concatenated to the PDF. The code above works on other PDFs we've had issues with in the past, so com.itextpdf.layout.Document does appear to be normalizing the coordinate space prior to drawing. Thus, the issue I describe above seems to be going undetected by itext?
• The rotation metadata in the PDF that itext7 reports from a "good" PDF without this issue seems to be the same as the rotation metadata in PDFs like the one I've linked above. This means I can't perform some kind of brute-force fix through detection.
• I would love any solution to not require me to flatten the PDF through any form of broad operation.
