SVG Slider example renders completely wrong This would need to be reduced to know exactly what is going on here.
This renders fine in Firefox and Opera. There are no messages in the console.
I suspect this is due to poor handling of <symbol>
Created attachment 10685 [details] Reduction This is a problem with dynamically inserting <use>. Using the DOM inspector you can see that the initial <use> has the symbol as its child, but the dynamically-inserted one is empty.
