Poseable mesh incorrectly rotates if "Set Bone Rotation by Name" is used in construction script

Using "Set Bone Rotation by Name" in the construction script of a blueprint using poseable meshes incorrectly rotates the mesh.

1. Download, unzip, open attached project
2. Open "BuggedSkelMesh" blueprint
3. In construction script, reconnect "Set Bone Rotation by Name" node
4. Press compile

Results:
In viewport, the skeletal mesh rotates 90 degrees

Expected:

No rotation occurs, blueprint compiles.
