Hi! I am trying to use svg images and serve them from the public/images folder. When using the url_for method I have to use the complete file name including the extension. Can you explain why?

Dear helpers, I have a question about the SVG device. It works fine, the SVG file is indeed produced, only the graphic differs from the R window. In the SVG file the dashed line is just a regular plain one.
