Description

**What you were expecting:**

Event drops zoom functionality to behave similar in all browsers

**What happened instead:**

With a large set of data the zoom is lagging in any version of IE.
It works fine on Chrome and Firefox

**Related code:**
I created a fiddle with a large set of data. you can test it in IE11 and see the difference when zooming with Chrome

Can you please suggest a solution for this (apart from using less data)? We need to be able to display big sets of data

Research direction

Start with the linked jsfiddle and reproduce zooming on the large dataset in IE11, then compare it with Chrome and Firefox. Trace the zoom behavior from the reproduction into the project’s JavaScript and identify the performance bottleneck; done means large datasets zoom with substantially less lag in IE without regressing other browsers.
