Sometimes it makes chart stop being responsive #439
Description
Reproduction: https://jsfiddle.net/wqc6mgyj/
If the chart is created with resizeDelay, sometimes the extension raises an error that makes the chart not responsive anymore.
When reproducing it in jsfiddle, sometimes it doesn't break, so I've also added the screenshot. (Refreshing and resizing window/fiddle panel might give different results)
Workaround: ...draw:function(t,e){var r,a,o,n,i,l;for(r=0,a=e ? .length;r<a;++r)...
As a workaround I've added ? after the undefined variable and it worked.
