Short description of error
Adding a shortcut key to an operator from Undo History adds the shortcut key to Undo History itself instead. For example, duplicate an object, open the undo history, right click the Duplicate Objects operator in the list and add a hotkey. The shortcut key is added but becomes a shortcut key to the Undo History instead of the actual operator. (Technically if the operator exists it should be Change Shortcut but you get the point)
Apart from that, opening the manual from there doesn't work either. No idea what Quick Favorites are but guessing that doesn't work either.
Anyway, if this was fixed it would be easier to add shortcuts for operators, instead of finding the right identifier and creating a new entry in the keymap you could just execute the operator, then open the undo history and add a key from there. (Of course it would be nice if you could just do this from the operator search window...)
Exact steps for others to reproduce the error
Based on the default startup or an attached .blend file (as simple as possible).
0. If no objects in the scene, add a cube.
- Duplicate an object.
- Open the undo history.
- Right click the Duplicate Objects operator in the list and add a hotkey.
Result: A shortcut key is added for Undo History.
Expected: A shortcut key is added for the right clicked operator (in this case Duplicate Objects)
