Nether portals extinguish fire of burning entities

Summary:
When I exit a nether portal while on fire, the fire is extinguished. This seems to be due to fire values being reset when entering the portal.

Steps to Reproduce:

1. Create a new world
2. Create a Nether Portal.
3. Enter the Nether Portal.
4. Exit the Nether Portal in the Nether.
5. Enter a nearby lava pool.
6. Exit the lava pool.
7. Enter the Nether Portal.
8. Exit the Nether Portal in the Overworld.

Observed Results:
Notice that the fire seems to have been extinguished.

Expected Results:
The fire is not extinguished.

Possible Solutions:
A possible solution is to make sure that fire damage values carry over and are not reset when entering a Nether Portal.
