Bedrock does not regenerate HP quickly at high hunger value

In the Java version, when hunger value is 20, the food scriber will reset to 0 when it reaches 10gt, and restore the player's food saturation ÷6 health, up to 1HP.
When hunger value is 18 or higher, the food scriber resets to 0 when it reaches 80gt and restores 1HP to the player.

This doesn't happen on bedrock.
