Blender Version
Broken: 2.8 2c2c996a1b and other previous versions

Short description of error

AUTO FK armature fails when trying to move it after having assigned another keyframe in DOPESHEET MODE/ACTION.

Exact steps for others to reproduce the error

Move around the character using AUTO IK without any keyframe being assigned
Create a keyframe for locrot for all bones
try to move the character using AUTO IK, it moves, but when you release the mouse, it comes back to the position of the keyframes assigned previously.

Observations:

If you only rotate the bones, it works as expected, but when you grab it does not.
I suppose its a problem with symetric bones with suffixes like _R, _L or .L or .R... IDK... Because spine bones work, but arms dont.
It came back to work after I have duplicated the armature and have reassigned the mesh to this new armature. But when I started animating it got broken again...
I happened in previous versions of 2.8 as well...

Here a video with it...

Tested something here... everytime you create a new action.. you need to press w and "clear user transforms" for it to work as expected.... is that a normal behavior?

Would kindly ask @angavrilov to maybe have a look (since he seems to be knee-deep in animation-related depsgraph?)

Otherwise (this is not using NLA), maybe @Sergey could also check on this?

This appears to be working correct now, solved along with the other keyframing bugs.
