System Information
Operating system: Windows-10-10.0.18362 64 Bits
Graphics card: GeForce GTX 970/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 430.86

Blender Version
Broken: version: 2.81 (sub 16), branch: master, commit date: 2019-11-06 20:48, hash: 85637311c2
Worked: (optional)

Short description of error
When undoing any operator after changing the view (if the view is locked to a camera)
the movement of camera is also undone with that operator

Exact steps for others to reproduce the error
View movement (when view is locked to camera) misses an undo push.

Can also be reproduced from the default scene:

{key Numpad 0} to go to camera view
enable View Lock > Camera to View
move the view
move the default cube
undo
movement of the camera is also undone

Original report

Toggle to camera view and lock the camera to the view.
Add Grease pencil object and draw strokes.
Move the view.
Stroke a line.
Undo the stroke. The movement of camera is also undone.

I attached a gif animation.

This can be a problem when I am thinking about layout and drawing simultaneously.

I can confirm.
This is seen with Grease Pencil or Annotation.
The same behavior is seen in blender 2.79

Not only a problem with grease pencil.

Lets put it that way: Should there be an undo push? Yes or No?
I can see both behaviors be somewhat problematic.
If we add an undo push here, we'll get many undo steps by view rotation (possibly also leading to unwanted behavior when working with operators).
Or is the user expected to not use Camera to View in that case?

Might be related to @BassamKurdali mentioning that autokey is not working in that scenario in https://devtalk.blender.org/t/2021-12-23-animation-rigging-module-meeting/22042
