Bottom half of "minecraft.png" title texture does not render

When using a resource pack to change the “minecraft.png” texture in “assets/minecraft/textures/gui/title”, the bottom half the texture is not rendered correctly. Fixing this bug would not affect the vanilla behavior as the vanilla minecraft.png does not have pixels drawn past that point, making this bug only affect creators.

Expected Behavior:

All pixels of the minecraft.png texture render should a resource pack use the entire sprite.

Result Behavior:

Only the top 176 pixels of the vertical space render the texture, and the bottom 80 pixels are invisible, even when a resource pack uses the entire 1024x256 space.
