The property of a component becomes read-only when it is bound to "PropertyStreamHandle"
Unity: Mecanim Animation
As Designed
2021.3.X
2020.3.X
Since animation writes back at every frame, it's expected that you won't be able to change the value.
Reproduction steps:
1. Open project “Repro.zip”
2. Open “SampleScene”
3. Enter Play Mode
4. Select the “Player” GameObject in the Hierarchy
5. Try to change the value of the "Value" property in the "Property Handle Test (Script)" component
Expected result: The value of the "Value" property can be changed.
Actual result: The value of the "Value" property cannot be changed.
