Description

Just added a driver to the alpha-property of an material. The Driver works fine, but the property is still "gray" and not as usually "purple", when it is connected to a driver. I appended a simple example, in which the alpha-property of the material is driven. It still shows the default state.

Here's the reason: Material drivers are currently being inserted in the "anim data" for objects, this to ensure a proper handling with animation dependency order (which is object based). If you insert a "key frame" you can see it's being added to the Material itself.

The UI does a quick lookup on a button draw if the button is animated, but it for this case the test fails.

it's not a trivial fix really, and certainly not something to do quickly. I've marked it on our todo list for future reference. It should definitely be implemented.
