Modifier tool is lost when scaling with "~" key held down
Fills can be modified without changing geometry if the "~" key is pressed during the operation.
Previous versions (at up to AI CC 2015) allowed the scaling process to be repeated indefinitely until another tool was chosen. In AI CC 2019 the "Scale" tool switches to the Pen tool every time the Mouse is released. This is a huge pain and should be fixed!! Keep the modifier tool active until another tool is selected please.
