Trimming an animation that uses root motion can cause the direction of the animation to appear off

After trimming an animation that includes a rotation in the begining the translation for the root motion appears to be applied as though the rotation had still been applied.

I have included the original fbx file. To reproduce this issue from scratch:

1. import that attached asset
2. Select the SK_Mannequin as the skeletal mesh
3. Import all
4. Open animation
5. Enable root motion
6. Enable Process root motion
7. Right click the time line
8. Remove frames 0-40

1. Download the attached project
2. Open the project
3. Open "m_std_crouch_to_crouchbw_01"
4. Enable "Process Root Motion" (Character > Animation > Process Root Motion)

Result: The animation appears to slide sideways as though the original rotation is still being applied after the animation has been trimmed
Expected: The animation would appear to be walking backwards
