Converting pdf to ppt with SeparateImages loses transparency

When converting attached file to powerpoint with SeparateImages=true options, individual images are rendered on white background when they should be transparent. When saved with SeparateImages=false, images are baked into one and look correctly.

On attached screenshot those words are rendered as images (I think that’s how that pdf is built).

var pdf = new Document(pdfFilePath))
var options = new PptxSaveOptions();
options.SlidesAsImages = false;
options.TryMergeAdjacentSameBackgroundImages = true;
options.SeparateImages = true;
pdf.Save(pptFilePath, options); (5.6 MB)
