The bug
If you light a creeper with a flint and steel, your "Mob killed" stat for "Creeper" will not increase.
How to reproduce
Take a Creeper and a flint and steel
Do a right-click with the flint and steel on the Creeper
→ ❌ Watch your stats of "Mobs Killed" before and after this action.

Can confirm in 1.17.1. Here is an alternate method of reproducing this issue:
Steps to Reproduce:
Create a scoreboard objective for tracking when you kill a mob and set it to display on the sidebar.
/scoreboard objectives add MobKills minecraft.custom:minecraft.mob_kills
/scoreboard objectives setdisplay sidebar MobKills
Obtain a sword and summon a creeper.
Kill the creeper using the sword.
→ ✔ Notice how the scoreboard increases.
Obtain a flint and steel and summon another creeper.
Use the flint and steel on the creeper to make it detonate.
→ ❌ Notice how the scoreboard doesn't increase therefore indicating that
minecraft.custom:minecraft.mob_kills
doesn't increase when killing a creeper through the use of a flint and steel.
Feature perhaps, you don't even kill the Creeper, just igniting it as TNT.
In a word, ignite =/= kill.
Still in 1.14.2 Pre-Release 1 and 1.14.2 Pre-Release 2
