Resolution Note:
This is by design. This field, along with many other integer fields in the same UI, is a 'delayed field'. The value isn't changed at all until you commit, usually by pressing return. The value is never set negative - the warning appears because the value is set to 1, which is too low for the scene.
The field is delayed so changes don't immediately take effect. Doing so can cause performance issues when dragging or editing the value.
You can type much more than just negative numbers. These types of field support arbitrary mathematical expressions. For example you could type `5-2`. You don't know that the actual value is 3 until you commit and evaluate the expression.
