System Information
Operating system: Linux-5.15.0-39-generic-x86_64-with-glibc2.35 64 Bits
Graphics card: Quadro GP100/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 510.73.05

Blender Version
Broken: version: 3.3.0 Alpha, branch: master, commit date: 2022-07-04 08:34, hash: 3f5073a8e2

Short description of error
In the timeline editor, under the Playback menu, you can enable "Show Subframes". If this setting is enabled you can scrub between frames.
The issue is that the operators to jump to the previous or next keyframe don't take subframes properly into account.
When using these operators the current frame will jump to the keyframe + the subframe offset within the same frame.
This makes the operator useless. It needs to jump to the exact keyframe location.

For comparison look at how the operators for jumping to the next/previous frame behaves. There it will snap back to the next full frame and remove the subframe offset.

Exact steps for others to reproduce the error

Add some keyframes when transforming the cube
Enable "Show Subframes" in the timeline editor
Scrub in the timeline
Use the up/down arrow keys to jump to the nearest keyframe
Zoom in and check the exact current frame / Check the transforms of the object (orange or yellow)
