How to set value of "trn-custom-data" for creating highlight annotations?

[arman]

When I create TextHiglightAnnotation by programmatically then it make difference from the default pdfjs highlight tool.

Here is my code.

const highlight = new Annotations.TextHighlightAnnotation();
        highlight.Author = annot.Author;
        highlight.Hidden = false;
        highlight.Quads = annot.Quads;
        highlight.StrokeColor = new Annotations.Color(255, 176, 176, 1);
        highlight.PageNumber = annot.getPageNumber();
        highlight.Locked = false;
        highlight.setCustomData("trn-custom-data", "Test Data");
        highlight.Subject = 'Highlight';
        annotManager.addAnnotation(highlight, true);
        annotManager.drawAnnotations(1);

Output:
