When exporting an SVG image to PDF, polylines with stroke-dasharray are rendered incorrectly — the dash pattern is not applied.

Additionally, polylines with a stroke-width exhibit visual artifacts such as pixelation or inconsistent thickness.

Step by step instructions or code snippets how to reproduce the problem

1. Save svg content (see below) as a file c:\test_svg_line_stroke.svg
2. Create an empty report
3. Add a picture box
4. Select a value for the picture box - use file c:\test_svg_line_stroke.svg
5. Go to preview - SVG is correct
6. Click Export->Acrobat (PDF) file and export a PDF file
7. Open PDF file to verify that the red line in a bottob does not have stroke-dasharray applied

If there's no black line with no stroke-dasharray - the red line in a bottom looks correct
