Bug (Case #1264038) Handles.ScaleHandle incorrect when center scaling

So just discovered this today. Not sure if it's present in other versions. But when using Handles.ScaleHandle, when center scaling and the input vector != 1, the returned result seems to either shrink or grow exponentially. Depending if > 1 or < 1. Issue doesn't occur with the individual axis scale handles.

the report I submitted just contains the exact script on the docs:
https://docs.unity3d.com/ScriptReference/Handles.ScaleHandle.html

And here's a video showing what happens:

I'm making very tiny adjustments, but the scale is seemingly increasing at exponential rate every time I release and scale again

 

Just tested 2019.4 and 2018.4

Issue does not occur in 2018.4 and does in 2019.4

 

Is there a workaround?
