Ender Dragon's lingering breath deals damage in Peaceful mode.

When playing on Peaceful difficulty, the player unexpectedly takes damage from the Ender Dragon's lingering breath particles after the dragon has been defeated. **Steps to Reproduce:** 1. Set the game difficulty to **Peaceful**. 2. Enter the End dimension (e.g., through an Ender portal). 3. Summon the Ender Dragon again by placing Ender Crystals (for a second or subsequent fight). 4. Defeat the Ender Dragon. 5. Walk into the lingering purple breath particles left by the dragon on the ground. **Expected Result:** The player should not take any damage from the dragon's breath, as the game difficulty is set to Peaceful. **Actual Result:** The player receives damage upon touching the dragon's breath particles. **Additional Information:** * This occurred during a second (or subsequent) Ender Dragon fight. * Observed near coordinates x=3, z=6
