The bug
If a chest with an enchantment glint is equipped on a mob which can have a chest equipped, the enchantment glint will not play. This is unlike saddles, which correctly show the enchant glint.
How to reproduce
Tame a donkey
/give @s saddle[minecraft:enchantment_glint_override=true]
/give @s chest[minecraft:enchantment_glint_override=true]
Equip both on the donkey
Expected results
Both the saddle and chest would display the enchantment glint.
Actual results
The saddle correctly displays the enchantment glint, but the chest does not.
How to fix
Make the chest rendering be handled by the equipment system; this would also fix MC-279508.
Further notes
Chests as items do not display the enchantment glint due to a bug; see MC-69683. This could be fixed by reopening and actually fixing MC-276877, as the item would then no longer be using the block entity rendering system.

...and how, exactly, is this a feature request?

Chest item stacks aren't even saved when equipped by donkeys.

This being labeled as a feature request makes no sense

Haykam, make a separate report for that, the whole item data is lost as a result of it just being a boolean. The chest is dropped at death, so it is reasonable to expect it to keep its data.
