Doors cannot be broken by swords in creative mode

What i expected to happen was for the door to break when i hit it with my sword.

What actually happened was only the particles came off the door, no evidence that the door was actually breaking other than that.

to reproduce:
1.enter creative mode.
2. place a door down (iron or wood, doesn't matter)
3. grab a sword (again, type doesn't matter)
4. try to break door with the sword
