Short description of error
In Sculpt Mode with the shortcut Alt + Shift + W it is possible to resize a face set after it was created. This is not working when geometry was previously hidden (for example via the shortcut H to isolate face sets).

• Create an object with enough geometry availibe
• Create face sets (for example with face set expand via Shift + W or the Draw Face Set Brush)
• Hide face sets via H or Shift + H or via the box mask tool
• Try resizing a face set via Alt + Shift + W
