Loading banners in Creative Menu for the first time since opening the game causes a short freeze

Basically, when you open the game, and you go into a world with creative mode, you open the decorations menu, and scroll down until you get to the banner layer, right before it loads the banners, it makes the game freeze for a few moments and then it will show the banners. After rendering the banners, this issue will no longer happen when trying to load them until the game is restarted.
