Map color for mangrove trapdoor is incorrect

The bug

The map color for mangrove trapdoors is incorrect. It appears brown like dark oak wood, instead of the expected red. This behavior is inconsistent with other wood types, which match the color of their trapdoors to the color of their other blocks.

How to reproduce

1. Obtain and fill a map
2. Place acacia doors, trapdoors, and fence gates
   All blocks appear orange
3. Place mangrove doors, trapdoors, and fence gates
   Only the trapdoors do not appear red

Expected behavior

The color of the trapdoors on the map would match the color of the other mangrove blocks on the map.

Actual behavior

The mangrove trapdoors appear brown on the map.
