Chrome

From the below attached image, you can see test-label axis label has more than one instance in dom.

Here is the behavior after few resize, the labels are getting duplicated and keep goes on.

How we are affected due to this issue:
We have some cases where we need to switch the axis labels between original label and modified label. Here we will show the modified label as axis label and show the original label as tooltip. Due to this multiple duplicated labels, we are unable to show the tooltip when we hover on it as the dom is occupied with the latest duplicated label (not allowing mouseover event).
