Bow and Shield render incorrectly when wearing Cape

The bug occurs when I equip my character's capes in the game. This bug is mostly visual, causing items like the bow and shield to malfunction in first-person view, making the experience unpleasant and causing me to dislike using the game's capes, even though I like having a custom cape that changes the elytra. It's a bug that has only occurred to me on mobile phones; it has never happened on other platforms like PS4 and laptops. Below I've included two images where in the first I'm without the cape and holding a shield and bow, while in the second image I'm wearing the cape and still have both items.
