(The third screenshot)
Confirmed today, thus I have to show the message in comments
The first screenshot was shot in 20w18a, the second was shot in 26.2-snapshot-5, and the third was shot in 20w17a.
Affects every version from 20w18a(when the death message “death.attack.fireworks.item” was modified) to 26.3-snapshot-5.
Confirmed in 26.3-snapshot-5
