System Information
Operating system: Linux-5.8.0-2-amd64-x86_64-with-debian-bullseye-sid 64 Bits
Graphics card: GeForce GTX 1070/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 450.66

Blender Version
Broken: version: 2.91.0 Alpha, branch: master, commit date: 2020-10-09 21:39, hash: 7ab8d7c939
Worked: not in 2.80 or 2.83

Short description of error
When the unit scale is too low (<= 0.002 for imperial, <= 0.00009 for metric) the stepsize is too big and sliding bound sliders (like thickness in solidify) will bounce them between their limits. At almost the same time seperate units stop showing the correct unit and instead switches to the default unit. But that seems to don't quite align as I was able to get the unit issue without the stepsize issue (might related to #81663).

The stepsize issue does not appear when Continuous Grab is disabled in the User Preferences.

Exact steps for others to reproduce the error
Based on default startup.

In Scene Settings: enable seperate units
set unit system to imperial with a unitscale of 0.001
add a solidify modifier and slide the thickness value
set unit system to metric with a unitscale of 0.00009
slide the thickness value of the solidify modifier again (same behavior)
disable Continuous Grab in the User Preferences
slide the thickness value of the solidify modifier again (normal behavior)
