The Bug:

Stripped death messages will remain in English (US) and will not be translated into the player's selected language.

Steps to Reproduce:

• Load the attached data pack into a dedicated server world (must be reproduced in multiplayer, not LAN).
• Change your language to a language other than English (US), such as German.
• Place all 5 written books unstacked in the renamed Shulker Box.
• Take the bow in your offhand, shoot up and at yourself while holding the Shulker Box in your main hand.
• Hover over the death message “was killed by even more magic”.

→  Notice that the stripped message is in English (US), ignoring the selected language.

Observed Behavior:

Stripped death messages will remain in English (US) and will not be translated into the player's chosen language, even though the string in question (death.attack.arrow.item) has been translated and approved for years.

Expected Behavior:

Stripped death messages will be translated into the player's chosen language and will not remain in English (US) for no apparent reason.
