When I select a Text Object and then use the Eyedropper Tool to sample any other type of object, it now applies a secondary set of Fill and Stroke higher in the Appearance hierarchy instead of just changing the Fill/Stroke of the Text Object, creating a Mixed Appearances problem.
I've included a lot of screen grabs. the 00 images are the initial object states.
From there, A is a drill-down use of the Eyedropper tool that produces the correct end result, but now with two more required steps.
B is by just using the Eyedropper, resulting in conflicting double application of Fill and Stroke.
UPDATE: This also occurs when applying to Groups and Compound Shapes.
UPDATE: This also occurs when applying to Layers.
In CS6 the eyedropper seems buggy when picking up colors to apply to text objects.
The way I get around the problem (includes the group and compound shape issue) is to expand appearance of the object (notice the ? in the object fill icon) and the immediately press the left carat (<) applying that last color picked.
