Loading Camel Dash texture glitches when a resource pack that has icons.png is enabled

Let's suppose you have a resource that contains an icons.png file (located in textures/gui). However, when riding a Camel, the bar that should appear of how strong the dash will be appears with a glitched and deformed texture of the icons.png from the texture pack used.

Steps to reproduce

1. Download the resource pack attached in this ticket.
2. Enable it, Join a world and spawn a camel.
3. Pick a saddle, equip in the camel and notice how the bar appears (if needed, hold the space bar.) 

Expected

The bar appears with the normal texture.

Actual

Instead, it appears with a glitched texture from the icons.png file.
