Previously, you could commence sprinting while gliding with an elytra, a functionality that worked consistently, even mid-air. However, for reasons unknown, this capability has ceased, rendering it also impossible to initiate swimming while gliding in water. Even attempting to start sprinting before gliding and then transitioning into water will discontinue sprinting due to MC-133414, thus preventing swimming while gliding, contrary to earlier versions. Even teleporing into water stops you from sprinting!
