Handles.ScaleHandle delta is now huge

Scaling individual axis works as expected. newScale = Handles.ScaleHandle(currentScale, handlePos, handleRotation, HandleUtility.GetHandleSize(handlePos));

However, in U2019.3, scaling all axes at the same time return huge numbers. Is this a bug or some kind of new (odd) behaviour?

Could you please submit a bug report with a sample project attached that displays the unexpected behaviour?
