When dragging a keyframe on top of another, it keeps both keyframes instead of overriding

When dragging a keyframe on top of another, it keeps both keyframes instead of overriding

• Create a Level Sequence
• Add a camera or any actor
• Add keyframes on the Transform track at different times with Snap to Interval on for Key and Playhead snapping
• Drag a keyframe over to another keyframe and let go of mouse

Expected: The dragged keyframe should be the one that replaces the old keyframe at the dragged time

Actual: Both keyframes exist at the same whole frame
