Glitch: Putting a Fire over a Poppy, or any flower that isn't 2 blocks high, will either make the fire disappear, with the Poppy, or the Fire just plainly making the Poppy disappear and elevates to the block under the Poppy once the Poppy disappears.
How to Re-Create:
1. Pop down a Poppy (See what I did there?)
2. Set fire to the top of the Poppy.
3. Watch to see if they both disappear, or the fire elevating.
I hope you found this cool
