This was discovered through reworking a test case. I noticed the bug when I was hitting crtl Z through all of my edits and noticed that the brush size value did not change even though the notification said it was undid. This also occurs when you change and undo Tool Settings as well.

Steps to Reproduce
  1. Create a new project
  2. * No Starter Content
  3. Press Shift + 3 to open Landscape Mode
  4. Set the Section size to 7X7 Quads
  5. Click Create
  6. Under Sculpt or Paint, change the brush size to a random number e.g. 500
  7. Click into the Viewport
  8. Press Crtl + Z

Result - A toast notification pops stating "Undo: Edit Brush Size" but the Brush Size Value does not change

Expected - The Brush Size changes back to the original value when Ctrl Z is pressed

Tested in 4.12.5 - the bug is present therefore not a regression.
