The Issue
The "Leave Bed" button that appears when sleeping in a bed covers both the health and hunger bars. This could be solved by moving the button a few upward so as to allow those bars to be shown, or having those bars move up above the button when it is present (second solution plays more nicely with Health Boost or Absorption).
Steps to Reproduce
Place down a bed.
Switch into survival mode.
Set the time to night.
Sleep in the bed.
Observed Behavior
The hearts and hunger bar are obstructed by the "Leave Bed" button.
Expected Behavior
The hearts and hunger bar remain visible while sleeping in the bed as it is important information for the player.
Confirmed.
