System Information
Operating system: Windows-10-10.0.18362-SP0 64 Bits
Graphics card: GeForce GTX 1060 3GB/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 461.92

Blender Version
Broken: 2.83LTS from steam, 2.92release and 2.93.0Alpha, branch: master, commit date: 2021-03-24 17:47, hash: 9ac7946dd0
Worked: don't know

Short description of error
Contrary to the manual, the "affect transform" option does not limit the transform values (not visible).
Also when using limit scale as a bone constraint the minimum scale is not used, instead uses maximum as both being the min and max exactly the same number but in negative value.

Exact steps for others to reproduce the error

Open attached file
Scale the bone beyond the limits
Note that the scale values in the transform panel have not been clamped.

I put a value for Minimum and I can say that it has an effect. However, positive limits are also considered to be negative limits.
This must be related to the "(!) Important" note in the manual:
https://docs.blender.org/manual/en/dev/animation/constraints/transform/limit_scale.html#bpy-types-limitscaleconstraint

But, as mentioned, the affect transform option doesn't really seem to be working, so I am confirming the bug.
