Hotbar/HUD is not visible when inventory is open
When the player's inventory or a container is open, the hotbar at the bottom of the screen is not visible. The inventory must be closed to view it again. This prevents you from seeing your health, hunger, and other important information.
How to reproduce
1. Put some items in your hotbar
2. Open your inventory

This can easily be fixed by setting "render_only_when_topmost" to false for the hud_screen element in ui/hud_screen.json.
This does cause a minor issue with the inventory player renderer when it is visible at the same time as the HUD paper doll, but otherwise causes no problems.
