Image show as black box starting with version 3.0.3

[seime]

Describe the bug

Png image (signature) stamped on PDF becomes black box. Worked well in 3.0.0, tested in 3.0.2 but broken in 3.0.3.

To Reproduce

Code to reproduce the issue

// Load image
URL resource = getClass().getResource(imageResource);
image = Image.getInstance(resource);
image.scaleToFit(80, 80);
...
// Open the existing PDF
PdfReader reader = new PdfReader(pdfTemplateStream);

// Create stamper for writing
ByteArrayOutputStream baos = new ByteArrayOutputStream();
PdfStamper stamper = new PdfStamper(reader, baos);

// Choose the page to modify (page numbers start at 1)
int pageNumber = 1;

// Get PdfContentByte for adding new content *above* existing
PdfContentByte canvas = stamper.getOverContent(pageNumber);

// Select a font
BaseFont font = BaseFont.createFont(BaseFont.HELVETICA, BaseFont.CP1252, BaseFont.EMBEDDED);

...
// Add to canvas
// content is just a simple wrapper for image + position
image.setAbsolutePosition(content.getX(), content.getY());
canvas.addImage(image);

Expected behavior

The image displays properly and not as a black box

Additional information

I see #1499 was merged between 3.0.2 and 3.0.3. It could be totally unrelated. While there could be a problem with either the image or the PDF I'm using, it used to work but not anymore.
