Tried MOB
/summon skeleton ~ ~1 ~ {HandItems:[{tag:{Enchantments:[{id:"flame",lvl:10s}]},id:"minecraft:bow",Count:1b},{}],HandDropChances:[0f,0f]}
Even if flame Lv is high fire extinguishes in about 4 seconds.
It should burn for a long time if it is original.

There is no effect for higher levels of flame. This is a feature request.

The flame arrow of the enchantment of the same Lv compared the player with the MOB,
and a difference was seen in flame time.
This is obviously a bug.
MOB flame-up time was similar flame time as minecraft 1.12.
The player's flame time will be extinguished in about 4 seconds at any Lv.
Please do not mark unreleased versions as affected.
You don't have access to them yet.
