At the same time some blocks, items and particles render over the background of nametags/renamed items in item frames/scoreboard... but not over the text (I don't know if this is a bug)
It's really easy to see if you change Text Background to Everywhere and change Text Background Opacity to 100%.
So far the blocks it happen to render over background that I know of are:
Heads and all variants
Glass and glass panes and all variants
Signs and all variants
Hanging signs and all variants
Beds
Banners
Item frames
Bell (only the Bell)
Decorated pots and all variants
Minecarts and all variants
Conduit
Chests and all variants
Beacon (only the ray)
Mobs (only the ones spawned with spawn eggs, weird!)
Dropped items
Particles
Others
There is another thing, when a player is sneaking near other players/nametags, it kinda blinks other nametags at the same time, but I was on a third party server, so it need further testing.
