Short description of error
When undoing first grease pencil stroke after changing view, if the view is locked to a camera,
the movement of camera is also undone with the first grease pencil stroke.

Exact steps for others to reproduce the error

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
