What I expected to happen was...:
Hitting a fire with a sword in creative mode wouldn't break it, as breaking other blocks in creative mode with a sword doesn't break them either
What actually happened was...:
The fire was broken
Steps to Reproduce:
1. Get in creative
2. Get any sword
3. Place some fire
4. Try to break it

Yeah apparently this is fixed as of MC-147708. You can no longer break anything with a sword.
