Small but annoying bug has been around since at least 2018.4, probably much longer. I'm on a Mac. Steps to reproduce: 1. New project 2. New Animator controller 3. New Blend tree, add a couple motions to it. 4. You should see a blue graph with a red line in inspector, edit one of the values underneath it to the left or right sides and press Enter or Return (don't click off). 5. Now anywhere you drag in the unity interface the value starts changing. Expected result in the value shouldn't change, pressing the Enter button should behave the same way as a click outside the field. See image.
