You might have tried to use an
<object> tag in JS Bin, i.e. for SVG, and noticed that nothing appears.
This appears to be a quirk in modern browsers (or certainly Chrome) where the
<object> can't be rendered inside and iframe (which we use for our real-time output).
The solution is to pop-out the output window (or open a new windown pointing to the same URL without
/edit on the end), and now the
<object> will render, and the window will live-reload as you code in the main edit view.
