   It seems to be a bug with SVG rendering in some Browsers. Tested with Chrome (failed), Firefox (failed), and Safari (OK) under Mac.
   Reported at https://bugs.chromium.org/p/chromium/issues/detail?id=1247310#c2
   
   Minimal SVG to reproduce:
   
   ```xml
   <svg xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" version="1.1" width="800" height="400">
       <path
           d="M 100 100 L 500 100"
           fill="none"
           stroke="red"
           stroke-width="3"
           style="filter: url('#f');"
       ></path>
       <defs>
           <filter id="f">
               <feDropShadow dx="20" dy="20" flood-opacity="1" stdDeviation="10 10"></feDropShadow>
           </filter>
       </defs>
   </svg>
   ``` 
   
   The above code renders nothing but if we change the `d` to be `d="M 100 100 L 100 200"`, it renders the line along with the shadow.
