Short description of error
Keyframe insertion by a Keying Set may fail during the edit mode when Keying Set channels refer to object data properties

Exact steps for others to reproduce the error
For example, object data properties such as mesh edge/face flags (e.g., use_seam and use_sharp) can be included in a Keying Set. Keyframing object data properties works fine in the object mode, but may fail in the edit mode when the properties to be keyframed have been updated since the last switching to the edit mode. The problem there is that the keyframed values are those at the time of switching to the edit mode, and not the updated values during the edit mode. In addition, the keyframe insertion operation reports a success that is not really the case.

From the applicative perspective, for now artists have to switch between the object mode and edit mode repeatedly while keyframing object data properties. That is a confusing and error-prone workflow.

Minimum steps to reproduce the reported problem:

Start with the factory scene with the default cube.
Go to the Scene tab of the Properties window, create a new Keying Set, and add a new path as follows:

Target ID block: Type = Mesh, ID = Cube
Data path: edges- .use_seam
Array target: All Items = disabled, Index = 0

Select the cube, enter the edit mode, and apply the Mark Seam command to the edge between two vertices at (1, 1, -1) and (1, -1, -1).
Stay in the edit mode and insert keyframes using the Keying Set by clicking the button to the right of the Active Keying Set entry in the Timeline window.
Switch to the object mode in the 3D View window.
Update the keyframed seam mark by incrementing the frame number and decrementing it.
Enter the edit mode again, and check if the seam mark has disappeared as reported above.

I will soon submit a patch to address the documented issue. Code review is duly acknowledged.
