Summary Double-click hangs browser when there are many SVG elements

The following HTML file reproduces the problem in Chrome and Safari. On page load a script inserts 15K SVG rectangles into the DOM. Then when you double-click on the completely unrelated div element the browser hangs for up to ten seconds before becoming responsive again. The duration of the hang seems to be proportional to the number of SVG rect elements in the DOM. When you insert many non-SVG elements there is no problem. ----- HTML ----- <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> </head> <body style="height: 100%; width: 100%;"> <div> <svg xmlns="http://www.w3.org/2000/svg" version="1.1" width="100" height="100" id="svg"><defs></defs></svg> </div> <div ondblclick="alert('That took a while');">Double-click here</button> <script> for (var i = 0; i < 15000; i++) { n = document.createElement('rect'); n.setAttribute('x', 0); n.setAttribute('y', 0); n.setAttribute('width', 100); n.setAttribute('height', 100); n.setAttribute('fill', 'blue'); document.getElementById('svg').appendChild(n); } </script> </body> </html>
