Oh god why, this is the best way I've found around it: add a spacebar (or your animation player key) hotkey entry that activates on RELEASE and toggles some dummy that creates a new undo history entry, I use wm.context_toggle on scene.render.use_stamp_frame_range, which is for file metadata and shouldn't cause any problems during rendering or sharing.

This guide exists because this annoying behavior seems to be in every version of blender, yet is not complained about anywhere online so I don't feel right filing a bug report over it. Damn it.
