Discrepancy in capsule distance to floor when crouching

When crouching is set in the CharacterMovement Component, the distance from the character capsule to the floor increases by one unit while crouching.

Regression:
No - Same behavior occurs in 4.16.3 (CL 3561208)

1. Open UE4 Editor (First Person Template)
2. Open FirstPersonCharacter blueprint
3. Select Movement Component and set Can Crouch in the details panel
4. Setup event graph as show in attached screenshot
5. PIE
6. Press Left Alt to crouch

Result:
~2.1 is printed to the screen while standing idle/walking but the number increases to ~3.1 while Left Alt is held

Expected:
Bottom of the capsule remains the same distance from the floor while crouching
