Comment (by Otto42):

 I put in a bug report with chrome:
 https://code.google.com/p/chromium/issues/detail?id=482998

 With an associated jsfiddle that demonstrates that problem:
 https://jsfiddle.net/7vo8wteu/

 Note that the fiddle works in Firefox too, with vastly different results.

 This doesn't change the problem here though. We still probably should
 ignore that clone div.
