When melee killed by a Blaze in survival the textbox message will not say it properly

What I expected to happen was...:
Text box saying: <playerName> Was burnt to a crisp while fighting a Blaze
What actually happened was...:
was slain by <plaayerName> / was burnt to a crisp whilst fighting a <playerName>

Steps to Reproduce:
1. Get melee killed by a blaze
2. Read the text box.
