This is a regression – in 4.27.2 the bracket keys do not change the Brush Size even though it is the default hot key. However, changing the hot key to something else works in 4.27.2.

Hot Keys are not working for Mesh Painting Brush Size. If the default '[' ']' keys are removed as a hotkey for everything else but mesh painting it still doesn't work. Changing the Hot Key to something different also doesn't work.

Steps to Reproduce
  1. Create or open any project
  2. Verify in Editor Preferences that Mesh Painting Brush Size has a Hot Key assigned
  3. In the Editor change the Mode to Mesh Painting
  4. With the Brush visible in the viewport press the Hot Key to increase or decrease the brush size 

Expected Results:
Brush size is increased or decreased as expected.

Actual Results:
Grid Snapping is changed. Brush Size does not.
