System Information
Operating system: Windows 10
Graphics card: NVidia GeForce RTX 2060

Blender Version
Broken: 2.90.0 Beta
Caused by 7b1c406b54

Short description of error
If a duplicated object has shapekey data, a unlinked duplicate of that object will have linked shapekey aniamtion data.

Exact steps for others to reproduce the error

With the default cube selected, in the ObjectData Properties tab of the Object Properties panel Add a Basis shapekey, and then add a second shape key
With the second shape key selected, enter edit mode and alter the default cube to give the shapekey some data
Exit edit mode
On frame 0, create a key frame on the shape key value
On frame 10, set the shape key Value to 1 and create a key frame
Duplicate the default cube and move the duplicate somewhere
Move the key frames on either the duplicate or the original, and see that the other's key frames are effected as though they were linked duplicates
Change the value of the key frames in the graph editor and see that the other's key frames are likewise altered as though they were also linked
Add a new keyframe. They both get the new one.

Near as I can find there is no way to make their key frames editable independently.

Transformation animations are not so linked.

Duplicating an object with animated shape key data seems to link to the same action:

As a workaround, you can right-click the key's action and "Make Single User".
But this seems like a bug to me, considering how User Preferences -> Editing -> Duplicate Data -> Action works just fine for object's actions.
